Question

15. In the figure, line AB is parallel to line CD and
line GH is the transversal.
Ifm/EFC = (3x + 25) and
mLGEB = (2x + 5),
then mZDFH = ?
(1) 135° (2) 65° (3) 115° (4) 120°​

Answer 1

Answer:

Step-by-step explanation:

GEB=AEF (vertically opposite angles)

So AEF+CEF =180 (Co. Int. Angle)

2x+5+3x+25=180

5x+30=180

5x=150

×=30
