Question

Find the measure of the missing angles b= c=

Answer 1

Answer:

b=20

c=160

Step-by-step explanation:

b has the same measurement as the other angle that is across from it. c is 160 because the line that c is on is a straight line so it is 180 degrees, you subtract the other angle on the line,20, then you get the answer.

Answer 2

Answer:

b = 20° ( vertically opposite angles are equal)

b + c = 180°

=> 20 + c = 180

=> c = 180 – 20

=> c = 160°
