Question

Find the missing side or angle.

Round to the nearest tenth.
A=18°
B= 28°
b=100
a=[ ? ]

Answer 1

It’s A 65.8 you are welcome

Answer 2

Answer: a = [ 65.8]

Explanation:

A = 18°

B = 28°

b = 100

a = [ x ]

`(100)/(sin \: 28^(o) ) =(x)/(sin \: 18^(o) ) \\\\(100)/(0.4694715628) =(x)/(0.3090169944) \\\\x=(0.3090169944 \cdot 100)/(0.469715628) \\\\x=65.78810\dots \\x \approx 65.8`
