Answer:

F= 34 degrees (alternate angles are equal)

To find D

we first have to find the angles at AB

B =180- 165 (sum of angles on a straight line = 180°)

therefore B = 15°(we'll use this to find the angle at E)

A=34 (from the diagram)

so,

D = 180- (15 + 34) [sum of angles in a triangle = 180°]

D = 131°

E=15° (alternate angles are equal )

Step-by-step explanation:

there u go!
