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

igomit [66]

Answer:

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
