Answer:
A. 3.5
Step-by-step explanation:
Given that AB is parallel to A'B', therefore,
CB/CB' = CA/CA'
CB' = 7
CB = CB' + BB' = 7 + BB'
CA' = 6
CA = CA' + AA' = 6 + 3 = 9
Plug in the values
(7 + BB')/7 = 9/6
(7 + BB')/7 = 3/2
Cross multiply
2(7 + BB') = 7(3)
14 + 2BB' = 21
Subtract 14 from both sides
2BB' = 21 - 14
2BB' = 7
Divide both sides by 2
BB' = 7/2
BB' = 3.5

Answer:
c) 60°
Step-by-step explanation:
We solve this question using trigonometric function of Cosine.
cos θ = Adjacent/Hypotenuse
θ = ???
Adjacent = Base of the ladder is on the ground = 2.5 feet
Hypotenuse = Length of the ladder = 5 feet
cos θ = 2.5/5
θ = arc cos (2.5/5)
θ = 60°
Therefore, the measure of the angle created by the ladder and the ground is 60°
