Question

My teacher gave us the answers but we just need to show the work for solving the problems. Please help me

Answer 1

12

Explanation:

58 = 5x - 2....because if the two lines are parallel the corresponding angles are congruent

58 + 2 = 5x

60 = 5x

`(60)/(5) = (5x)/(5)`

x = 12

hope it helps

for any question comment me ❤❤
