Answer:

Step-by-step explanation:

z = 62

The reason it is 62 is because it is equivalent to the other side of the lines.

x = 73

15 + 58 = 73

Hope this helps!

Answer:

x = 4, z = 62

Step-by-step explanation:

z and 62 are vertical angles and congruent, hence

z = 62

z and 15x + 58 form a straight angle and are supplementary, hence

15x + 58 + z = 180, that is

15x + 58 + 62 = 180

15x + 120 = 180 ( subtract 120 from both sides )

15x = 60 ( divide both sides by 15 )

x = 4
