Answer 2

Step-by-step explanation:

PM is perpendicular So Angle PMB = 90°

<c + 20° = 90°

<c = 90°-20°

<c = 70°

<PMB + <d = 180° (straight line is 180°)

<d = 180° - 90°

<d = 90°

Now since CD intersect AB

so,

<a = 20° (vertically opposite angle)

<a + <b = 180° (straight line is 180°)

20° + <b = 180°

<b = 180° - 20°

<b = 160°

Hope you get it
