1. What is a formula that can be used to find the area of one triangular section of the door?
2. How do you know the formula will work?
Answers
Answer:
\(A=\frac{ab}{2}\) or \(A = a *\sqrt{c^2-a^2} /2\)
Step-by-step explanation:
Depending on the values you take depends on the equation you would use to solve for the area of a right triangle(the first answer accounts for measuring both arms(the sides connected to the 90 degree angle(a and b)), where as the second answer accounts for using the hypotenuse and one of the arms). That means that a 90 degree angle is involved, or as illustrated here, the square in the bottom right corner. If this were a non-right angle triangle, a different formula utilizing the height of the triangle would be used instead.
\(A = \frac{h_{b}+b}{2}\)
Since the right angle exists, a height is already given using one of the arms of the triangle in its place. We can also confirm it is a triangle by adding up all degrees of the triangle, in which it would equal 180 degrees confirming it is indeed a triangle as well.
By using trigonometric relations we will see that the area is:
How to find the area of one triangular section?
Remember that the area of a right triangle is equal to the product between the cathetus divided by 2.
Sadly, here we don't have the measures of any sides of the triangle, so getting the actual area is impossible, but if we assume that some dimension is given (like the height, let's say that is h).
h is the cathetus adjacent to the 60° angle, then the other cathetus (the bottom one) is given by:
tan(60°) = x/h
x = tan(60°)*h
Then our two catheti are h and tan(60°)*h.
This means that the area will be:
Here we only used trigonometric properties, so this area will work for any height given (always that the value of h is the cathetus adjacent to the 60° angle).

Answers
Answer:
D is the right choice and no you cannot fit the pizza inside the box.
Step-by-step explanation:
D is the answer because to turn 2/3 into a decimal you would divide 2 by 3 and the answer you would get would be 0.66666666666...You would then add 12 to the answer and get 12.6666... Once you get this answer you would round it to the hundredths to get 12.67 but since that is not an option you could use D, 12.66 inches.

The equation below can be used to find the length of a foot or forearm when you know one or the other.
(length of the foot) = 0.860 • (length of the forearm) + 3.302
If you let y = length of the foot and x = length of the forearm, this equation can be simplified to
y = 0.860x + 3.302.
Using this equation, how long would the foot of a person be if his forearm was 17 inches long?
Answers
Answer:
length of foot = y
length of forearm = x = 17
Equation: y = 0.860x + 3.302
Plug in 17 for x in the equation, and simplify. Remember to follow PEMDAS, first multiply, then combine like terms:
y = (0.860)(17) + 3.302
y = 14.62 + 3.302
y = 17.922
length of foot = y = 17.922 inches long
Step-by-step explanation:
If the forearm of a person is 17 inches long then his foot would be 17.922 inches long.
What is an equation?"It is a mathematical statement which consists of equal symbol between two algebraic expressions."
For given question,
We have been given an equation y = 0.860x + 3.302
y = length of the foot and x = length of the forearm
The equation below can be used to find the length of a foot or forearm when you know one or the other.
We need to find the foot of a person be if his forearm was 17 inches long.
For x = 17 inches, we need to find the value of y.
Substitute x = 17 in the given equation.
⇒ y = 0.860x + 3.302
⇒ y = 0.860 (17) + 3.302
⇒ y = 14.62 + 3.302
⇒ y = 17.922
Therefore, if the forearm of a person is 17 inches long then his foot would be 17.922 inches long.

The required answer is ⅖¹³.

We can see here that two terms have same base that is ⅖ . And the other is 5/2. So for simplifing the expression we will use some laws of exponents , which are :-
a ^m + aⁿ = a^{m + n }a -ⁿ = ( 1/a )ⁿUsing these we have ,
\(\bf = \dfrac{2}{5}^8 \times \dfrac{2}{5}^{-2}\times \dfrac{5}{2}^{-7} \\\\\bf= \dfrac{2}{5}^8 \times \dfrac{2}{5}^{-2}\times \dfrac{2}{5}^7 \\\\\bf= \bigg(\dfrac{2}{5}\bigg)^{(8+7-2)}\\\\\boxed{\red{\bf= \dfrac{2}{5}^{13}}}\)

Angle B and angle C are supplementary. If the measure of angle B is 14 times the measure of angle C, what is the measure of angle B?
Enter your answer as the correct value, like this: 42
explain why
Answers
Answer: the difference between the angles is 156
Step-by-step explanation: firstly, you need to assume that C is variable X
by that you can say that B is 14X , since B is 14 times C which we assumed is X
and since they are "supplementery" then the addition of those angles will be 180 degrees so by saying B+C=180° which is the same is (14X)+X=180° you can find X (C)
then multiply the result X(C) by 14 to get angle B
then subtract the angles B and C and you're done
Step-by-step explanation:
We know that Angle B + Angle C = 180
If B is 14 times greater that means B = Angle C x 14. That means Angle C = 180/ Angle B.
Which also equals to Angle C = 180/ Angle C x 14. Angle C =. 180/15 which means Angle C = 12. If Angle B + Angle C = 180 that means Angle B = 168. 168-12= 156

Suppose you pick a marble at random without looking. Find the probability of the event.
Answers
Answer: A 1/5
Step-by-step explanation:
Probability of getting blue marble, red marble, white marble, and purple marble are 1/4, 2/5, 1/5 and 3/20 respectively.
What is probability ?
Probability shows possibility to happen an event, it defines that an event will occur or not. The probability varies from 0 to 1.
Given that,
Number of blue marbles = 5,
Number of red marbles = 8,
Number of white marbles = 4,
And number of purple marbles = 3.
Total number of marbles = 5 + 8 + 4 + 3 = 20
Probability of getting blue marble = number of blue marbles/total number of marbles
=5/20=1/4
Apply same formula,
Probability of getting red marble= 8/20 = 2/5
Probability of getting white marble = 4/20 = 1/5
Probability of getting purple marble = 3/20
