Given: Two angles form a linear pair. One angle is 22 degrees more than the other.
Required: Measure of the smaller angle.
Explanation:
Let x be smaller angle.
The second angle is 22 degrees more, so second angle is (x+22)
Since they form a linear pair, so their sum is 180 degrees
![\begin{gathered} x+x+22=180 \\ 2x+22=180 \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/fhezucwge4narkoym9zpgxceigbwoipbeo.png)
Solving further
![\begin{gathered} 2x=158 \\ x=79 \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/a3lcihpvp7yqwnsuv2oiufu3egxldfepbh.png)
So the smaller angle is 79 degrees.
Final Answer: Option D is correct answer.
