Question

Find the missing side or angle.

Round to the nearest tenth.
C=53°
B= 80°
a=2
b=[?]

Answer 1

2.69 approximately 3

Explanation:

53⁰+80⁰+A=180⁰(sum of angles on a triangle)

133⁰+A=180

A=180-133

A=47⁰

using sine rule

2/sin 47 = b/sin 80

b sin47 = 2 sin 80

b= 1.9696/0.7314

b=2.69 approximately 3
