What is the area of the trapezoid?

Alecsey [184]

Area of trapezoid:

A = 1/2(b1+b2)h

where

b1 = 30,

b2 = 28+12 = 40

Triangle FOG

a^2 = c^2 - b^2

a^2 = 13^2 - 12^2

a^2 = 169 - 144

a^2 = 25

a = √25

a = 5

FO = 5 so height h = FO = 5

Now you can find the Area of trapezoid

A = 1/2(b1+b2)h

A = 1/2(30 + 40) (5)

A = 1/2(70)(5)

A = 175

Answer

175 square units

The volume of the cylinder by definition is given by:
V = pi * r ^ 2 * h
Where,
r: radio
h: height
Substituting values we have:
V = 3.14 * (14/2) ^ 2 * 4.5
V = 692.37 ft³
Answer:
the volume of the pool is:
V = 692.37 ft³

Which equation can be used to find the length of Line segment A C? Triangle A B C is shown. Angle A C B is 90 degrees and angle

taurus [48]

Answer:

AC = 10sin(40°)

Explanation:

The diagram representing the question is shown in the attached image

Since the given triangle is a right-angled triangle, we can apply the special trig functions

These functions are as follows:

sin(θ) = opposite / hypotenuse

cos(θ) = adjacent / hypotenuse

tan(θ) = opposite / adjacent

Now, in the given diagram:

θ = 40°

AC is the side opposite to θ

AB = 10 in is the hypotenuse

Based on these givens, we will use the sin(θ) function

Therefore:

$sin(40) = \frac{AC}{10}\\ \\AC = 10sin(40)$
