Answer:
p=-4/3+q/3
Step-by-step explanation:
<u>Answer-</u>
<em>The distance d across the lake is </em><em>90ft.</em>
<u>Solution-</u>
In the picture,
ΔABC ≈ ΔCDE
Because,
- ∠ACB = ∠DCE (∵ vertical opposite angles)
- ∠B = ∠D = 90°
- ∠ACB = ∠CED (∵ as other two angles are same and sum of those two angles when subtracted from 180° will result the same)
So, from similarity properties
