Answer:

x = 22, m<B = 88

Explanation:

1) Finding the missing side. This is called a supplementary angle.

A = 180 - 132

A = 48°

2) Solving for the x

Triangle: a + b + c = 180°

4x + 2x + 48 = 180

6x + 48 = 180

6x = 180 - 48

6x = 132

x = 132/6

x = 22

Your answers and the question are correct.

Proof:

4(22) + 2(22) + 48 = 180

88 + 44 + 48 = 180

180 = 180
