What is the measure of {ced and {acd?

Part a)

Part b)

Step-by-step explanation:

step 1

Find the measure of angle ACB

we know that

The sum of the measures of interior angle of a triangle must be equal to

so

In the triangle ABC

step 2

Find the measure of angle ACD

we know that

-------> by supplementary angles

we have

substitute

step 3

Find the measure of angle CED

we know that

m<DCE=m<ACB ------> by vertical angles

so

Remember that

The sum of the measures of interior angle of a triangle must be equal to

so

In the triangle CDE
