Answer:
61.08m
Step-by-step explanation:
Let " l " be the length of the rope and " θ " the angle at which it is raised. In other words:
- l = 65m
- θ = 70°
As you can see, there has been made a right angle triangle. So:
So the kite is approximately 61.08m above the ground.
In order to find the sin70° i used a calculator.
Using it's concept, it is found that the domain for the expressions is, respectively, given by:
It is the <u>set that contains all possible input values</u>.
In a fraction, the denominator cannot be zero, hence:
- The domain of the first two expressions is of
.
- The domain of the last expression is of
.
The third expression can be simplified, as:
(x + 5)/(x + 5) = 1.
The same is true for the fourth, as:
x²/x = 1.
Neither has any restriction, hence their domain is all real numbers, represented by .
