Question

Find the measure of the missing angles.

Answer 1

e = 41 , f = 139 and d = 90

Explanation:

?

Answer 2

We know that vertically opposite angles are equal.

So, e = 41° [Vertically opposite angles]

We know that linear pair of angles are supplementary (180°).

So, f + 41° = 180° [Linear pair of angles]

=> f = 180° - 41°

=> f = 139°

and d + 90° = 180° [Linear pair of angles]

=> d = 180° - 90°

=> d = 90°
