Answer:
The kite is 109.7 ft off the ground.
Step-by-step explanation:
Raul is flying a kite at the end of a string that is 250 feet long.
Raul is holding the string 4 feet off the ground at the angle to the horizontal as shown in the attached diagram.
We want to find out how high is the kite off the ground.
Recall from the trigonometric Identities,
Here we are given the hypotenuse that is 250 ft and opposite is the unknown height
We know that Raul is holding the string 4 feet off the ground so
105.7 + 4 = 109.7 ft
Therefore, the kite is 109.7 ft off the ground.

<h3>4 times a number increased by 3.</h3>
When we have a number that appears
right before a variable, it means multiplication.
So 4n means the same thing as 4 times a number.
Remember, n is a variable which is just a
letter that represents any number.
Since we are adding 3 to 4n, we can say
4 times a number increased by 3.
So 4n + 3 can be written as 4 times a number increased by 3.
