Question

What's the answer to b = and c =

Answer 1

Answer:
b = 21°
c = 159°

Explanation:

To solve for B we have to know that the opposite angle is the same. So 21° is the same as angle b.

To solve for C we have to know that a line adds up to 180°. So 21° plus c = 180

To find this we do 180 - 21 = 159.

Answer 2

B = 21

C = 159

Explanation:

As we are given 21 degrees as one of the angles, we can also notice that both lines are straight, so they are both adding up to an angle of 180 each.

To find C, we can use this equation:

C + 21 = 180

C = 180-21

C = 159

To find B, we can use this equation:

B + C = 180

Plug in C:

B + 159 = 180

B = 180-159

B = 21
