Question

The sides of an isosceles triangle are 19,19,and 16yd long. What is the area of the triangle. Do not round any intermediate computations and round your answer to the neares tenth

Answer 1

use Pythagoras theorem to find the height and the rest is easy

Answer 2

the base is 16, base/2 is 8 (this will be a leg of a right triangle)
we need height to solve for area of triangle
(height^2 + 8^2)^(1/2) = 19^2
solve for height
then use it in area formula of triangle which is
base * height / 2 = area

do i need ot solve it completely? just matter of plug in numbers here

Answer 3

herons formula?
