In the diagram below, line AB is parallel to line CD. The measure of ∠∠ABC is 28° and the measure of ∠∠EDC is 42°. Find the measure of∠∠CED. Explain why you are correct by presenting an informal argument that uses the angle sum of a triangle.

what is the measure of ∠∠CED is ? And Explain why ?

CED=110

Step-by-step explanation:

ab and cd are ll

so abc is equal to bcd (alt. int. angle)

sum of tri comes it bc a tri= 180 just subtract 42 and 28

the answer is:

the answer is:

to solve the problem, we need to remember the quotient of power property, it's defined by the following relation:

if we have a quotienf of powers that have the same base, we need to keep the same base and subtract the exponent of the denominator power to the exponent of the numerator power.

so, we are given the expression:

then, calculating we have:

hence, the answer is:

have a nice day!
