Answer:
45.6
Step-by-step explanation:
The set up is right angled
Length of the ladder = Hypotenuse = 35ft
Height of window = opposite = 25ft
Using SOH CAH TOA
sin theta = opp/hyp
sin theta = 25/35
sin theta = 5/7
theta = arcsin(5/7)
theta = arcsin()0.7143)
theta = 45.6
Hence the angle of elevation is 45.6
