Vertical component = 8 x sin(95) = 7.970 (4sf)
Horizontal component = 8 x cos(95) = -0.6972 (4sf)
I think its 48m^2 I hope it's correct
Answer:
≈ 35.1 ft
Step-by-step explanation:
The model is a right triangle with ladder being the hypotenuse and the angle between the ground and the ladder is 70°
Using the cosine ratio, with l being the length of the ladder.
cos70° =
=
( multiply both sides by l )
l × cos70° = 12 ( divide both sides by cos70° )
l =
≈ 35.1 ( to the nearest tenth )
The ladder is approx 35.1 ft long
I believe that the answer is B and D
