Chapter 12: Q29. (page 696)

Tell whether the angles are complementary, supplementary, or neither.
$\begin{matrix} m ∠ 1 = 140 ° \\ m ∠ 2 = 40 ° \end{matrix}$

Short Answer

Expert verified

The pair of angles are supplementary to each other.

Step by step solution

Step 1. Given Information.

The choices are: complementary, supplementary, or neither.

Step 2. Concept used.

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

Step 3. Calculation.

Calculate the sum of the measures of the two angles.

$\begin{matrix} m ∠ 1 + m ∠ 2 = 140 ° + 40 ° \\ = 180 ° \end{matrix}$

Step 4. Conclusion.

Since the sum of angles is $180 °$ , the given two angles are a supplementary angle pair.
