1 answer:
Answer: the height of the helicopter is 22.33 yards
Step-by-step explanation:
The diagram illustrating the scenario is shown in the attached photo. A triangle, ABC is formed.
H represents the height of the helicopter.
x + y = 52
x = 52 - y
We would apply trigonometric ratio.
tan # = opposite side/adjacent side.
Tan 48 = H/x
H = xtan48
H = tan48×(52 - y)
H = 1.1106(52-y)
Also,
Tan 35 = H/y
H = ytan35
H = 0.7002×y
H = 0.7002y
Since H = H, therefore
1.1106(52-y) = 0.7002y
57.7512 - 1.1106y = 0.7002y
0.7002y + 1.1106y = 57.7512
1.8108y = 57.7512
y = 57.7512/1.8108
y = 31.89
Recall,
H = 0.7002y
H = 0.7002 × 31.89 = 22.33 yards

Question is Incomplete, Complete question is given below.
Latanya and George are saving up money because they both want to buy new bicycles. Latanya opened a savings account with $50. She just got a job and is determined to save an additional $30 a week. George started a savings account with $75. He is able to save $25 a week. Find the time (in weeks) when Latanya and George will have the same amount of money in their savings accounts.
Answer:
Latanya and George will have same amount after 5 weeks.
Step-by-step explanation:
Given:
Opening Amount in account of Latanya = $50
Amount deposited every week = $30
Let number of week be 'w'.
Total Amount in Latanya savings account will be equal to Opening Amount plus Amount deposited every week multiplied by number of week.
framing in equation form we get;
Total Amount in Latanya savings account =
Also Given:
Opening Amount in account of George = $75
Amount deposited every week = $25
Let number of week be 'w'.
Total Amount in George savings account will be equal to Opening Amount plus Amount deposited every week multiplied by number of week.
framing in equation form we get;
Total Amount in George savings account =
Now we need to number of week when both will have same amount.
Now to find number of week when both will have same amount we need to make both the equation same we get;
Hence Latanya and George will have same amount after 5 weeks.
