<h3>Given</h3>
right triangle with side "a" = 12 and hypotenuse "c" = 15
<h3>Find</h3>
cos(∠A)
<h3>Solution</h3>
The Pythagorean theorem tells you
... b = √(c² - a²) = √(225 - 144) = √81 = 9
The definition of the cosine tells you
... cos(A) = b/c = 9/15
... cos(A) = 3/5 . . . . . . reduce the fraction
Answer:
9 inches
Step-by-step explanation:
The volume of a pyramid is given as:

where l = length of base of pyramid
w = width of base of pyramid
h = height of pyramid
The volume of the cylinder is already known (
) and the other two dimensions are known as 5 in and 7 in.
From the formula of the volume of the pyramid, the height of the pyramid is given as:

Hence, the height of the pyramid is:

The pyramid's height is 9 inches.
