Question

A cat owner has a scratching post that is shaped as a right triangle as shown in the illustration. It is 26 in. tall with a base of 28 in. She wants to build a larger scratching post in the same shape that will be 39 in. tall. Lumber is sold in even-foot lengths (6 ft, 8 ft, 10 ft, etc.). Find the lengths (in inches) of the three sides of the larger scratching post and determine what length of lumber she must purchase to build it. (Round your answers using the rules for working with measurements.)

Polygon with three sides, three angles, and three vertices. Based on the properties of each side, the types of triangles are scalene (triangle with three three different lengths and three different angles), isosceles (angle with two equal sides and two equal angles), and equilateral (three equal sides and three angles of 60°). The types of angles are acute (less than 90°); obtuse (greater than 90°); and right (90°).
