Answer:
The angle of PML is 68°.
Step-by-step explanation:
Given that total angles in a straight line is 180° so we can assume that ∠LMN is 180°. In order to find ∠PML, we have to subtract :
[tex]∠PML+∠ PMO + ∠OMN = 180[/tex]
[tex]∠PML + 90 + 22 = 180[/tex]
[tex]∠PML + 112 = 180[/tex]
[tex]∠PML = 180 - 112[/tex]
[tex]∠PML = 68[/tex]
