NOTE: Angles not necessarily drawn to scale.

Answer: 60°
Step-by-step explanation:
- the two angles created by CD and EF are vertical angles so they are equal
- one angle is 30° so the other one is 30° and it splits an existing 90° angle so 90-30 = 60 so x is 60°
hope this helps :)
Answer:
∠x=60°
Step-by-step explanation:
Add 90° and 30° then subtract by 180 to find ∠x.
How I got 30 degrees is because of the vertical angle. Vertical angles are always equal.
I got the 90 degrees from the left top side.
180 degrees is the degrees of a straight angle.
90+30=120
180-120=60
Hope this helps!
If not, I am sorry.
