Question

Find the length of side b in ëABC to the nearest whole number if A = 42ô, B = 87ô, and a = 24.

Answer 1

Given triangle angles A = 42 ,B = 87

Given side a = 24

From the law of Sines a/SinA = b/SinB = c/Sinc

a/SinA = b/SinB

24/Sin(42) = b/Sin(87)

24/0.66 = b/0.99

Multiple to each side by 0.99.

b = 36.36*0.99

b = 36.31

Lentgth of b = 36
