Question

The sketch shows two parallel lines cut by a transversal. Angle 1 is 58° . What is the measure of angle 7 ?

Answer 1

We know that
∠1=∠5------------> by corresponding angles are congruent
so 
∠5=58°

and
∠5+∠7=180----------> by supplementary angles
so
∠7=180-∠5--------> 180-58--------> 122°

the answer is ∠7=122°

Answer 2

Answer: 122
