A kite is flying 100 feet off the ground, and its string is pulled taut. The angle of elevation of the kite is 57°. Find the length of the string. Round your answer to the nearest tenth. Do not include units in your answer and round correctly (one decimal place!)

83.9feet

Step-by-step explanation

Using SOH, CAH, TOA to solve the problem;

The problem will form a right angled triangle

Let the length of the string be the hypotenuse

Let the length of the kite be hypotenuse = 100ft

Using SOH;

Sin57° = opposite/hypotenuse

Sin57° = opp/100

Cross multiply

Opp = 100sin57°

Opp = 83.87feet

Hence the length of the string is 83.9feet to one decimal place

$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)
