Solve the right triangle B = a = C =

Solution

let angle C = 90 degrees

A = 40

therefore, by triangle property sum of angles = 180 degrees

angle B = 180 - ( 90 + 40) = 50 degrees

applying law of sines to find the side length

a / sin A = b / sin B = c / sin C

a / sin 40 = 25 / sin 50

a = 20.97

c / sin 90 = 25 / sin 50

c = 32.63
