Question

Given the indicated parts of triangle ABC with 𝛾 = 90°, approximate the remaining parts. (Round your answers to the nearest tenth.)

a = 31,    b = 9.0

𝛼	=	°
𝛽	=	°
c	=

Answer 1

tan(alpha) = 9/31

alpha = 16.2 degrees

beta = 90-16.2 = 73.8 degrees

side opposite the 90 degree angle squared = 81+ 961 = 1042

c = 32.3
