Question

Given that L1 || L2, find the measures of angles a and b when 0 = 43°

Answer 1

Answer:

a = 43 degrees

b = 137 degrees

Step-by-step explanation:

according to the alternate interior angle theorem, angle a equals angle theta, so angle a = 43 degrees

angle b is the supplement of angle a, so angle b = 180-angle a, or 137
