A circular arc has measure 5 in and is intercepted by a central angle of 41 degrees. Find the radius r of the circle. Do not round any intermediate computations, and round your answer to the nearest tenth.

the 2 figures are congruent bc if you reflect abcd over the y axis then over the d axis the figures overlap

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet
