Question

An isosceles triangle has area of 120 ft squared. If the base is 16 ft, what is the length of each leg? Round your answer to the nearest tenth

Answer 1

use the area formula to find the height. Then use the pythagorean theorem to find the leg (hypotenuse of the right triangle).

Answer 2

so am i suppost to get 15?

Answer 3

A = .5bh

120 ft^2 = .5(16)h

h = 15

15/2 = 7.5

I think you're supposed to get 7.5.

Answer 4

\[\frac{1}{2}(16)h=120\]
\[h=15\]
