Answer:
m<CBD = 68 degrees
Step-by-step explanation:
Add both of the given angle measures and set them equal to 90 degrees.
4x + 52 + 8x - 10 = 90 Combine like terms
12x + 42 = 90
- 42 - 42 Subtract 42 from both sides
12x = 48 Divide both sides by 12
x = 4
Now plug this into the equation for m<CBD
4(4) + 52 Multiply
16 + 52 Add
68 degrees
