Question

What is the area of "triangle " XYZ to the nearest tenth of a square inch? Use special right triangles to help find the height. Show your work.

Answer 1

That is a 30 60 90 triangle.

In such a triangle the "middle" size = short side * sq root (3)

height = 5 * sq root (3) = 8.6602540378

Area = (1/2) * 5 * 8.6602540378

Area = 2.5 * 8.6602540378

Area = 21.6506350946 square centimeters

Answer 2

A=24√3

Put In Decimal Form:41.5692193817^3

Explanation:

4 Inches on short side, this means that the long side is 8 inches because the short side is always 1/2 the length of the long side, The medium side length is 4√3. So you need to take the short side and medium side and multiply them by 1/2, look below for how to do it.

A=1/2(4)(4√3)

2(12√3)

24√3
