25. You have to do 65x65-(60x60) and the square root it
The missing side is 12. The scale factor is 1/5.
Answers:
32/100 = 16/50 = 8/25
72/100 = 36/50 = 18/25
43/100 = 43/100
29/100 = 29/100
This question needs more information like where point E is but I'm going to assume that point E is directly below point D
With that assumption, angle EDF should be (90°- 25°) which is 65°
tan 65° = opposite/adjacent
tan 65° = 10 yd/ DE
DE = 10 yd/tan 65°
DE = 4.7 yd (to the nearest tenth)
Remember to include a picture next time for greater clarity :)
