This is the concept of trigonometry, the distance from the foot of the ladder will be given by:
tan theta=[opposite]/[adjacent]
opposite=17 ft
adjacent=x ft
theta=37°
thus
tan 37=17/x
x=17/tan 37
x=22.56 ft
=22.6 ft (to the nearest 10th of a foot)
In step one, you are supposed to add 25 to both sides, because if you just subtract, it would be -5x-50=53
Answer:
Cost for skii: J(x) = 30x + 7
Cost for beach chair: B(x) = 5x + 3
=> Total cost = J(x) + B(x) = 30x + 7 + 5x + 3 = 35x + 10
=> Option C is correct.
Hope this helps!
