Answer:
x = 45
Step-by-step explanation:
We know that the sum of (x+30) and 75 are vertical angles so they are equal
x+30 = 75
Subtract 30 from each side
x+30-30 = 75 -30
45
Step-by-step explanation: since the lines form a Z that means if you add 30 by another number it will equall 75 so to get the number subtract 3o from 75 and you'll get 45
