Find b. given that a = 20, angle a= 30°, and angle b = 45° in triangle abc.
a = 20
300
45
10_2
20/2
20/3
4022

The value of b is 28.28

Step-by-step explanation:

We would use Law of sines to find the value of b

The law of sines is:

We are given

a= 20

A = 30°

B = 45°

b=?

Putting values in the formula:

The value of b is 28.28
