Suppose you live 4.4 miles from a hill. From your home you see a plane directly above the hill. Your angle of elevation to the p

IrinaVladis [17]

█ Explanation █

Let's call the missing altitude 'x'.

✦ To find the plane's altitude, find the tan of 30 degrees. The side opposite is going to be x, while the side adjacent is going to be 4.4 miles.
✦ $Tan(30)= \frac{x}{4.4}$
✦ $5.7735= \frac{x}{4.4}$
✦ $x=4.4*.57735$
✦ $x=4.4*.55735$
✦ $x=2.54 mi$
✦ We usually write altitude in feet.

Answer: 2.54 * 5280 ~ 13,400 ft

A right triangle has a hypotenuse of length 99 inches. if one angle is 34 degrees34°, find the length of each leg.

Andreyy89

Sine (34) = opposite / 99
opposite side = .55919 * 99
opposite side = 55.35981 

Adjacent side² = 99² - 55.35981²
Adjacent side² = 9,801 -3,064.7085632361 
Adjacent side² = 6,736.29 
Adjacent side = 82.0749

Sunday elementary school is having its annual Read a thon. the third graders have read 573 books so fair. Their goal is to read

il63 [147K]

The answer would be 901 because they said what is the least number they would need to read and their goal is MORE than 900. The amount of books that they already had is useless information (Ignore). They love giving trick questions. :)
