Find the area of this triangle. It is a right triangle with the angle to the right being 72 and the base being 19cm.

Answer 1

You will need the height of the triangle which you can calculate using tangent function

Tan 72 =x/19 x= 19tan72= x = 58.48

Area of a triangle is (1/2) base x height = (1/2) (19) (58.48)=555.5cm
