A kite is flying 79 ft off the ground, and its string is pulled taut. The angle of elevation of the kite is 50°. Find the length
Art [367]

Answer:

If the kite has an 11 ft line attached to it and it casts an 8 feet shadow, we will have a rectangle triangle (see picture below).

To find the height x of the kite, we can apply the Pythagorean theorem.

x² = 11² - 8²

x² = 121 - 64

x² = 57

x =√57

What percent of 60 is 27? <br><br>22 is 55% of what? ​
DerKrebs [107]

For this question, set up an equation.  60 times what decimal is 27?

60x=60

x=0.45

Convert this decimal to a percentage by multiplying it by 100:

45%

For this question, set up an equation.  55% (or 0.55) times what number equals 22?

0.55x=22

<em>*Divide both sides by 0.55*</em>

x=40

Hope this helps!!
