10.) Kelly is flying a kite to which the angle of elevation is
1 answer:
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.

Answer:
3, -8
(x is equal to 3 and y is equal to -8)
Step-by-step explanation:
<u>The system:</u>
{ 7x=-67-11y
{ 5x=-73-11y
<u>Finding a value for x:</u>
7x=-67-11y -> x = -
<u>Solving for y by plugging in our x:</u>
[Equation] 5x = -73 -11y
[Plug-in] 5( -
) = -73 -11y
[Distribute the 5] -
= -73 -11y
[Multiply by 7] 7 ( -
) = (-73 -11y) 7
[Simplify] -335 - 55y = -511 - 77y
[Add 335 and 77y to both sides] 22y = -176
[Divide by 22] y = -8
<u>Plug in our y to solve for x:</u>
5x = -73 -11y
5x = -73 -11(-8)
5x = -73 + 88
5x = 15
x = 3
