Answer:
ABD = 49 DEGREES
CBD = 28 DEGREES
Step-by-step explanation:
Add ABD AND CBD equations TOGETHER
8x+5=77
Subtract 5 both sides.
8x=72
x=9
Now you have x, this isn't all you have to do, put x into the equations you have.
3(9)+22=?
27+22= 49
ABD = 49 degrees
5(9)-17=?
45-17= 28
CBD = 28 degrees
to check work, 49 + 28 = 77
