The problem says that <span>Brandon sights a helicopter above a building that is 200 feet away at an angle of elevation of 30 degrees. So, you can calculate the height asked, by following this procedure:
</span>
Tan(α)=Opposite leg/Adjacent leg
α=30°
Opposite leg=x
Adjacent leg=200 feet
When you substitute these values into the formula above (Tan(α)=Opposite leg/Adjacent leg), you have:
Tan(α)=Opposite leg/Adjacent leg
Tan(30°)=x/200
You must clear "x":
x=200xTan(30°)
Therefore, the value of "x" is:
x=115 feet
<span>
How high above the ground the is the helicopter?
The answer is: 115 feet</span>
Answer:
Both Oscar and Kim will have enough to purchase the book.
Step-by-step explanation:
Oscar takes 30% of the normal price and subtracts it from the normal price. Out of 100% price he takes 30% so the result is: 100-30%= 70% of the normal price. Oscar's first step has the same result as Kim.
Oscar takes 10% of the discounted price (70%) and adds it back. The price will become 70% + 10%*70%= 77% of original price. Kim multiplies the discounted price with 110%, so the price will be: 70% * 110%= 77%. Both also give the same result.
The final price is 77% of the original, it will be: $28.50* 77%= $21.945
Oscar :
28.50 - 0.30(28.50) = 28.50 - 8.55 = 19.95
0.10(19.95) + 19.95 = 2 + 19.95 = 21.95
Kim :
0.7(28.50) = 19.95
1.10(19.95) = 21.95
So if 18 + x =43, then what you need to do is
18 + x =43
-18 -18
——————
x = 25
because whatever you do to one side, you need to do to the other

Step-by-step explanation:
A law that says that if the temperature is constant then the volume of a fixed amount of a gas is <u>inversely proportional</u> to its pressure.If the pressure on a gas increases, the volume of the gas decreases because the gas particles are getting closer together.
Answer:
5
Step-by-step explanation: BECAUSE IN A PARALLELOGRAM OPPPOSITE SIDES ARE EQUAL SO IF THE PERIMETER IS 33.2 WE SHOULD SUBTRACT THAT NUMBER WITH 11.6*2 WHICH IS 23.2 SO 33.2-23.2 WHICH IS 10,SO 10/2 IS THE OTHER SIDE OF THE PARALLELOGRAMWHICH IS NOTHING BUT 5
