Circumscribed 5465

Inside the rectangle ABCD, the points E and F lie so that the line segments EA, ED, EF, FB, and FC are congruent. Side AB is 22 cm long, and the circle circumscribed by triangle AFD has a radius of 10 cm. Determine the length of side BC.

Correct answer:

b =  16 cm

Step-by-step explanation:

a=22 cm r=10 cm x=(ar)/2=(2210)/2=6 cm r2 = x2 + (b/2)2 b=2 r2x2=2 10262=16 cm
