Identify a trigonometry function that represents the relationship between the kite string, it's height off the ground, and the angle of elevation of the sun. Find the height of the kits

Sine;

Step-by-step explanation:

The figure is included below as attachment. A right-angled triangle is formed by considering the variables mentioned in the statement of the problem. The trigonometric function that uses all the mentioned variable is the sine, which is:

Where:

- Angle of elevation of the sun.

- Height of the kite off the ground.

- Length of the kite string.

The height of the kite can determined by clearing the corresponding variable in the previous formula:

answer: 5

step-by-step explanation:

all three statements are true

step-by-step explanation:

a shipping fee of 5% is charged online with every item purchased online

first let's just take each option and calculate them based on this, to see if the answers matched

keith buys a 40 dollar book

40 x 0.05 = 2

therefore there will be a two dollar fee on keith's book

40 + 2 =42

the first statement is true

a chair costs $80

80 x 0.05 = 4

80 + 4 = 84

the second statement is true

george buys a 20 dollar calculator

20 x 0.05 = 1

20 + 1 = 21

the third statements are true

all three statements are true
