Question

A special triangular frame is being made for a piece of artwork. The the base of the triangular frame must be 90 cm. If the area of the triangular frame is 765 square cm, what is the height? a) Let h = the height of the triangle. Write the equation you would use to solve this problem.

Answer 1

Answer:

Explanation:

base of triangular frame, b = 90 cm

Area, A = 765 cm²

Let the height is h.

Area of a triangular frame = 1/2 x base x height

765 = 0.5 x 90 x h

h = 17 cm

Thus, the height of triangular frame is 17 cm.
