Question

an angle measures 81°. find the measure of its supplement and the measure of its complement select the correct choice below and, if necessary, fill in the answer box to complete your choice a the measure of the supplement of a 81° angle is \\(\square\\)° (simplify your answer. type an integer or a decimal.) b. there is no supplement.

Explanation:

Step1: Calculate supplement

Supplementary angles sum to $180^\circ$.
$180^\circ - 81^\circ = 99^\circ$

Step2: Calculate complement

Complementary angles sum to $90^\circ$.
$90^\circ - 81^\circ = 9^\circ$

Answer:

A. The measure of the supplement of a 81° angle is $99^\circ$.
The measure of the complement of a 81° angle is $9^\circ$.
