Question

Find the unknown angle measured

Answer 1

b=121, a and c=59

Explanation:

b and 121 are congruent angles, so they are equal to each other.

each side of a line equals 180 degrees, so subtracting 180-121=c gives you 59 degrees.

a and c are congruent angles so they are also equal to each other

Answer 2

B= 121
A= 59
C= 59
I hope this helps!
