Question

In the diagram below of triangle ABC, D is the midpoint of AC and E is the

midpoint of BC. If m/CB A = 16 + 6x, and m/CED = 48 - 2x, what is the
measure of ZC BA?

Answer 1

Answer: 40 degrees

Explanation:

m/CBA = m/CED

16 + 6x = 48 - 2x; add 2x on both sides and subtract 16 on both

8x = 32; divide 8 on both sides to isolate the x

x = 4

m/CBA = 16+6(4) = 40
