Find b, given that a = 20, angle a = 30°, and angle b = 45° in triangle abc

b = 20√2

Step-by-step explanation:

Given: ΔABC

           a = 20 , m∠A =  30° and m∠B = 45°

To find: value of b.

We use Sine result, which state that

Substituting given values we, get

we know that , we get

Therefore, b = 20√2

b
