Answer:
Length of the ramp = 18.6 feet (Approx.)
Step-by-step explanation:
Given:
Horizontal distance (base distance) = 17 feet
Angle of elevation = 24°
Find:
Length of the ramp
Computation:
Cosθ = Length of base / Length of hypotenuse
Cos 24 = Horizontal distance (base distance) / Length of the ramp
Cos 24 = 17 / Length of the ramp
0.9135 = 17 / Length of the ramp
Length of the ramp = 17 / 0.9135
Length of the ramp = 18.6 feet (Approx.)

Answer:
A
Step-by-step explanation:
Find AB using the Law of Sine:
Thus:
Multiply both sides by sin(40)
AB = 31.0056916 ≈ 31.0 cm (nearest tenth)
the scale factor used in Emily scale drawing is K = 1.63 mm/m
<h3>
What scale did Emily use?</h3>
We know that Emily drew a scale drawing of a house and its lot.
In the scale drawing, the back patio is 42 millimeters long, and we know that the actual patio is 27 meters long.
Then the scale relates the measures 44mm and 27 meters, such that if the scale is K, we can write:
K*27m = 44mm
Solving for K, we can write:
K = (44/27) mm/m = 1.63 mm/m
So the scale factor used in Emily's scale drawing is K = 1.63 mm/m
