In a right triangle ABC, C = 90°, b = 380.1 inches and c = 589.1 inches. Solve for all the missing parts using the given information. (Round each answer to one decimal place for side and to two decimal places for angles.)

A = °

B = °

a = inches

You have a right-angled triangle , so basic trig is needed here

Make a sketch

looks like cosA = adjacent/hypotenuse = 380.1/589.1 = .64522....

Angle A = 49.82°

B = 90° - A , you do that one

sinA = a/589.1

a = 589.1sin 49.82 = 450.0
