Answer:
48°
Step-by-step explanation:
Overall, it's 360°. If you add 90° (the right triangle), x°, x°, 2x, 30°, and x° you will get 5x + 120. Subtract 120 from 360, and you will get 240. Once you get 240, you divide by 5, to solve for x.
x = 60 Degrees
Using the vertical angle theorem -->
we can conclude Ang. COB = Ang. AOD -->
Convert into an equation -->
30 + 2x = 90 + x
Combine like terms and solve
2x = 60 + x
x = 60
--> thus, x is equal to 60 degrees
Hope this helps!
