By using trigonometric relations, we will see that the angle of elevation must be 55°.
<h3>
How to find the angle of elevation?</h3>
We can see this as a right triangle, where one cathetus measures 1250ft (altitude) and the other cathetus measures 875ft.
The angle of elevation is the angle such that the adjacent cathetus is the one measuring 875ft.
Then we can use the relation:
tan(a) = (opposite cathetus)/(adjacent cathetus)
tan(a) = 1250ft/875ft
To find the angle of elevation, we can use the inverse tangent function:
a = Atan(1250ft/875ft) = 55°
The angle of elevation must be 55 degrees.

Answer:
3 cups of cream
2 cups of chocolate
Step-by-step explanation:
9/3 = 3
1 x 3 = 3
2 x 3 = 6
6+3 = 9
Answer:
if she has 17 quarters, the money of it would be $4.25.
$5.05 - 4.25$ = $0.80
=> 8 dimes
=> she have 17 quarters and 8 dimes
Step-by-step explanation:
Answer:
17. x = y^2 - 2ay +a^2
18. x = y^2 - a
Step-by-step explanation:
17. Since we want to make x the subject of the formula, we first isolate the square root of x and get
= y - a.
squaring both sides,
x = y^2 - 2ay +a^2
18. Since both x and the a are under the square root, we first start by squaring both sides.
So y^2 = x+a.
Isolating the x, we get
x = y^2 - a
I think it’s 1/6 or 0.16, those two are basically the same thing
