Chapter 12: Q22. (page 690)

Use the given information to find $m ∠ 2$ .
$∠ 1$ and $∠ 2$ aresupplementary angles, and $m ∠ 1 = 137 °$ .

Short Answer

Expert verified

The measure of angle $m ∠ 2$ is $43 °$ .

Step by step solution

Step 1. Given Information.

$m ∠ 1 = 137 °$

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.

Since $∠ 1$ and $∠ 2$ are supplementary angles.

$\begin{matrix} m ∠ 1 + m ∠ 2 = 180 ° \\ 137 ° + m ∠ 2 = 180 ° \\ m ∠ 2 = 180 ° - 137 ° \\ = 43 ° \end{matrix}$

Step 4. Conclusion.

The measure of the angle that is supplementary to an angle measuring $137 °$ is $43 °$ .
