Chapter 12: Q14. (page 689)

Tell whether the angles are complementary, supplementary, or neither.

m鈭�1=71掳m鈭�2=19掳

Short Answer

Expert verified

The pair of angles are complementary to each other.

Step by step solution

01

Step 1. Given Information.

The choices are: complementary, supplementary, or neither

02

Step 2. Concept used.

If the sum of two angles is 90掳 then the angles are called complementary angles and if the sum is 180掳 then the angles are called supplementary angles.

03

Step 3. Calculation.

Calculate the sum of the measures of the two angles.

m鈭�1+m鈭�2=71掳+19掳=90掳

04

Step 4. Conclusion.

Since the sum of angles is 90掳, the given two angles are a complementary angle pair.
