Question

what error did tyler make? m∠1 = 72 by same - side exterior angles theorem x while there is no same - side exterior angles theorem given, same - side exterior angles are supplementary, not congruent. m∠1 = (do not include the degree symbol in your answer.) video textbook get more help.

Explanation:

Step1: Recall supplementary - angle property

Same - side exterior angles are supplementary, meaning their sum is 180 degrees.

Step2: Set up the equation

Let the measure of the given angle be 72 degrees and the measure of ∠1 be \(x\). Then \(x + 72=180\).

Step3: Solve for \(x\)

\(x=180 - 72\).
\(x = 108\)

Answer:

108
