ACE is an isosceles triangle. What is the measure of <CDB​

Answer 1

Side CB is 125 degrees and CD is also 125 degrees. The base will still be 180.

Answer 2

Answer: 55 degrees

Step-by-step explanation:

Triangle ACE is isosceles, and so is triangle BCD because we have similar triangles (use the AA theorem to prove this).

The diagram shows angle ABD = 125.

Angle DBC = 180 - (angle ABD) = 180-125 = 55 degrees, which is also the measure of angle CDB because the base angles of isosceles triangles are congruent.
