Answer:
answer is ........ C
Step-by-step explanation:
We just use the sinus rule to calculate this
a / sin alpha = b / sin beta
Alpha is the 90 degree angle from the wall to the floor
beta is the angle from the top of the ladder to the wall,
wich is 90 degrees - 75 degrees (triangle has 180 degrees angles, one is 90 degrees), so beta = 15 degrees
14 foot / sin 90 = b / sin 15
sin 90 = 1
we move the sin15 over to the other side
14 foot x sin 15 = b
b = 3.62 foot
15:24
divide both sides by 3
b. 5:8
for 6:30
divide both sides by 6
1:5
52 weeks = 1 year
104 weeks = 2 years
Once: 475/104 = $4.57 per visit
Twice: 475/104x2 = $2.28 per visit
Five Times: 475/104x5 = $0.91
