Using the technique in the model above, find the missing side in this 30°-60°-90° right triangle.
short = 5 , hypotenuse = 10
long =

In 30-60-90 triangles, the:

Hypotenuse = short side * 2

Longer leg = short side * √3

So since you are solving for the longer leg, multiply the shorter leg by √3.

5 * √3 = 8.66

Longer leg = 8.66

$53.50

step-by-step explanation:

you have to subtract the amount of money chuck earned ($72.50) by the cost of the gas for the mower ($11.25) and the new string for the trimmer he bought ($7.75).

72.50-11.25=61.25

and then subtract $61.25 by the second thing he bought (the new string for the trimmer)

61.25-7.75=53.5

so in total it's $53.50 (53 dollars and 50 cents)
