Question

Please help me. I’ve been stuck on these questions all day.

Answer 1

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
