A 30 ft ladder leans against the side of a house. If the base of the ladder sits 10 ft away from the base of the house, what is
the ladder's angle of elevation?
1 answer:
Answer:
70.5°
Step-by-step explanation:
To solve for the ladder's angle of elevation, we solve using the Trigonometric function of Cosine
= cos θ = Adjacent/Hypotenuse
Where
Adjacent = Distance of the base from the house = 10ft
Hypotenuse = Length of the ladder = 30 ft
cos θ = 10/30
cos θ = 1/3
θ = arc cos 1/3
θ = 70.528779366
Approximately = 70.5°
Therefore, the ladder's angle of elevation is 70.5°

Step-by-step explanation:
Answer:
2.25
Step-by-step explanation:
Area = 525
A_1 = L X W = 9 * 28 = 252
A_2 = L X W = 18 * 14 = 252
A_3 = L X W = 7 * 3 = 21
A = A_1 + A_2 + A_3 = 252 + 252 + 21 = 525
Answer:
x <= 10, x >4
Step-by-step explanation:
This is because 4 is less than 10 and 10 is greater than 4, making them overlap
