A helicopter is at a cruising height of 1,200 feet. Suppose the angle of depression to the landing pad is 15°, which is located

on top of a building that is 64 feet high. If the helicopter continues at the current cruising height, how far does the helicopter need to travel to be directly above the landing pad? Include a sketch that shows all known information and clearly shows what you need to find. Show all work and give the answer rounded to the nearest foot.

Answer:

we have a right triangle and to get the internal angle of the right triangle formed at the helicopter we subtract 62 degrees from 90 which equals 28 degrees

we now use the cosine to find the distance (d) from the helicopter

cosine 28 = 85/d

d = 85 / cosine 28 = 85 / 0.8829 = 96.2736 = 96 feet

Leto [7]

Answer:the distance from the headquarters from a point on the ground directly below the balloon is

175 feet

Step-by-step explanation:

The right angle triangle ABC formed is shown in the attached photo. C represents the position of the balloon.

A represents the position of the ranger headquarters.

x represents the distance from the headquarters from a point on the ground directly below the balloon.

1 minute = 0.0167 degrees

Converting 43' to degrees, it becomes 43 × 0.0167 = 0.7181

Angle A = 66 + 0.7181 = 66.7181 degrees.

We would apply trigonometric ratio

Tan # = opposite side/ adjacent side

# = 66.7181 degrees.

opposite side = 1106

Tan 66.7181 = 1106/x

6.324 = 1106/x

x = 1106/6.324

x = 175 feet

Billys empolyer for 65% of his annual health insurance permiu. Billy has the rest deducted equal amounts from his paycheck. If B
Delvig [45]

Answer:

His employer contributes with $4712.53 towards his health insurance on an annual basis.

Step-by-step explanation:

With the information provided, you know that Billy's employer pays 65% of his health insurance premium and you can subtract this from 100% to know the percentage that Billy has to pay:

100%-65%=35%

Also, the information states that Billy has $105.73 withheld from his paychecks twice each month and you can multiply this for 24 to find the total amount that he pays per year and that represents 35%:

$105.73*24=$2537.52

Finally, you can use a rule of three to found the amount that represents 65% which would be what his employer pays given that $2537.52 represent 35%:

2537.52 →  35%

     x       ←  65%

x=(2537.52*65)/35

x=$4712.53

According to this, the answer is that his employer contributes with $4712.53 towards his health insurance on an annual basis.
