15 Points!! Is this my teacher's fault? The math and the picture aren't making sense. The blue is my answer.
kogti [31]

Answer:

Your teacher is correct.

Step-by-step explanation:

So first we would have to find what A is equivalent to which is 48. This is because 180 - 132 = 48. Since we know that 132 is a supplementary angle, there has to be another supplementary angle that results in the sum of 180.

With this information in mind, we can create the expression:

2x + 4x + 48 = 180 (A triangle is equal to 180 degrees)

Now simply the equation:

6x + 48 = 180

6x = 132

6x/6 = 132/6

x = 22

Angle C = 44

Angle B = 88
