Question

Using the diagram on the right, what would the measure of Angle c be if Angle a=55.

c=59

c=90

c=116

c=66

Answer 1

Answer:  c=59 degrees.

Step-by-step explanation:

57 + d + 64 = 180

121 + d = 180

-121        -121

        d = 59

Angle d is alternate interior to angle c so they are congruent.
