Akite on a 160-foot string is caught on a pole. when the full length of the string is stretched in a straight line to the ground, it touches the ground a distance of 50 feet from the bottom of the pole. the string forms an angle of ° with the ground when it is stretched like this.

String form an angle of 18.2° with the ground.

Step-by-step explanation:

Given: Length of the string of a kite = 160 ft.

           Kite stuck on pole at height of = 50 ft.

We need to find: Measure of angle formed by string of kite with ground.

Attached figure showing the given situation.

let α be the required angle.

In ΔABC,

using trigonometric ratio,

Therefore, String form an angle of 18.2° with the ground.

b

step-by-step explanation:

given

- 2 (3x + 12y - 5 - 17x - 16y + 4 )

simplify the parenthesis by collecting like terms

= - 2 (- 14x - 4y - 1) ← distribute the parenthesis by - 2

= 28x + 8y + 2 → b

$450 is the answer.

step-by-step explanation:

30% of 450 = 135

450-135=315
