Awall in maria’s bedroom is in the shape of a trapezoid. the wall can be divided into a rectangle and a triangle.

a trapezoid is shown. a straight line with length h is drawn to the opposite side to form a right angle. it splits the shape into a rectangle and a triangle. the length of the hypotenuse is 13 startroot 2 endroot feet. the other angles of the triangle are 45 degrees.

using the 45°-45°-90° triangle theorem, find the value of h, the height of the wall.

6.5 ft
6.5 startroot 2 endroot ft
13 ft
13 startroot 2 endroot ft
