A helicopter flying 3590 feet above ground spots the top of a 150-foot y'all cell phone tower at an angle of depression of 77° h
erik [133]

Answer:

794.19 feet.

Step-by-step explanation:

Please find the attachment.

Let x be the distance helicopter needs to fly to be directly over the tower.

We have been given that a helicopter flying 3590 feet above ground spots the top of a 150-foot y'all cell phone tower at an angle of depression of 77°.

We can see from our attachment that helicopter, tower and angle of depression forms a right triangle.

As height of tower is 150 feet, so the vertical distance between helicopter and tower will be 3590-150=3440 feet.

We cab see from our attachment that the side with length 3590-150 feet is opposite and side x is adjacent side to 77 degree angle.

Since we know that tangent relates the opposite side of a right triangle to its adjacent side, so we will use tangent to find the length of x.

\text{Tan}=\frac{\text{Opposite}}{\text{Adjacent}}

Upon substituting our given values in above formula we will get,

\text{Tan}(77^o)=\frac{3590-150}{x}

\text{Tan}(77^o)=\frac{3440}{x}

x=\frac{3440}{\text{Tan}(77^o)}

x=\frac{3440}{4.331475874284}  

x=794.1865\approx 794.19

Therefore, the helicopter must fly approximately 794.19 feet to be directly over the tower.

Which graph represent the solution set of this inequality
VashaNatasha [74]
Hi!

First, let me explain that open circles mean that the answer starts after or before that number. So if the answer is q < 4, the answer would be C, and not B. 

If the answer was q ≤ 4, the answer would be B, and not C. 

I hope that makes sense. Now let's solve the inequality.

Remember that whatever we do to the inequality, we have to do it to both sides. 

We need to isolate q on one side.
11q + 5 ≤ 49
Start by subtracting 5 from both sides.
11q + 5 - 5 ≤ 49 - 5
11q ≤ 44
Divide by 11 on both sides.
11q/11 ≤ 44/11
q ≤ 4

The answer is B.

Hope this helps! :)
