Explanation
By the Pythagorean theorem, 
Tanα=h/x
x=h/tanα
x=70/tan38 ft
x≈89.6 ft (to nearest tenth of a foot)
Note: the question seems strange, (because this would make the ladder almost 114 feet long!) or are we to assume as I did that the ladder is leaning against a point 70 feet high, or should if be a 70 foot ladder leaning against a wall of unknown height?
If it is just a 70 ft ladder at a 38° inclination the:
cosα=x/L
x=Lcosα
x=70cos38° ft
x≈55.2 ft
Answer:
49 cupboards
Step-by-step explanation:
See the steps below, it is self-explanatory:
- 4 men ⇒ 4 days ⇒ 4 cupboards
- 4 men ⇒ 1 day ⇒ 1 cupboard
- 1 man ⇒ 1 day ⇒ 1/4 cupboard
- 14 men ⇒ 1 day ⇒ 14/4 cupboards
- 14 men ⇒ 14 days ⇒ 14*14/4 cupboards
As 14*14/4= 49, the answer is 49 cupboards
Answer would be x = 1/3 and y = 5
I believe it's E.) 12.96
12 times 8% equals .96 so $12.96 should be the answer since it wants the final price with tax :DD
