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

constant acceleration- a

constant velocity- c

no velocity or acceleration- b

explanation:

for body moving with a constant acceleration, the rate of change of displacement changes over time. this is proven by the increasing gradient of the curve (a) against time.

a body that is moving at constant velocity covers equal distances over equal periods of time, thus the straight line with a constant gradient c.

a stationary body   covers no displacement as time elapses. thus the flat line with   zero gradient.

seems like d
