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>
Wait for area, wouldn't you just times 13 and 5 and get 65 and then times 23?
Answer:
About 1205.12352941 people per square mile in 2010
About 1329.36306853 people per square mile in 2015
Explanation:
take population and divide by land area
for 2015 pop do total pop divided by 9.7 plus total pop
4x(5x3)=(4x5)x3 the associative property basically just moves the parentheses.
