A rectangular exercise mat has perimeter of 48 feet. The length of the mat is twice the width. Write and solve an equation to determine the length, in feet, of the mat.

In triangle △abc, ∠abc=90°, bh is an altitude. find the missing lengths. ah=4 and hc=1, find bh.

Cot(90° − x) = 1 the value of x that satisfies this equation is °. a. 60 b. 135 c. 225 d. 315
