We're going to  use trigometric functions! 

So we know the angle is 63° (Ф=63°)
the length of the string is 45 ft (hyp=45)
and we need to solve for height (h=?)

Using sinФ=\frac{opposite}{hypotenuse}

We can rewrite it as
sinФ=\frac{height}{hypotenuse}

By isolating the height (h) we can find the value
sinФ=\frac{height}{hypotenuse}
h= hyp(sinФ)

Then insert value of hyp, Ф and find height
h= hyp(sinФ) = 45sin63 = 40 ft

The kite is 40 ft off the ground

Solve the right triangle​
grandymaker [24]

Answer:

HJ = 5.20

HI = 3

angle J = 30 degrees

Step-by-step explanation:

sin 60 = HJ/6

HJ = 5.20

cos 60 = HI/6

HI = 3

angle J = 90-60 = 30 degrees

If f(x) = 16x – 30 and g(x) = 14x – 6, for which value of x does (f – g)(x) = 0?
andre [41]

The value of the x will be 12. The value of the x is obtained from the condition,(f – g)(x) = 0

<h3>What exactly is a function?</h3>

A function is a statement, rule, or law that specifies the connection between two variables. Functions are common in mathematics and are required for the formulation of physical connections.

Given function;

f(x) = 16x – 30

g(x) = 14x – 6

⇒(f – g)(x) = 0

⇒(16x – 30)-(14x – 6)=0

⇒16x-30-14x+6=0

⇒2x-24=0

⇒x=24/2

⇒x=12

Hence, the value of the x will be 12.
