Replace f(x) with y:
y = 5x-6
Swith the variables:
x = 5y -6
Now solve for y:
add 6 to each side:
x +6 = 5y
Divide both sides by 5:
y = (x+6)/5
Now replace y with the inverse function f^-1 (x):
f^-1(x) = (x+6)/5
The balloon's vertical distance above the ground is 430 feet.
<h3>What is the angle of depression?</h3>
You look straight parallel to the ground. But when you have to watch something down, then you take your sight down by moving your head up.
The angle from horizontal to the point where you stopped your head is called the angle of depression.
From a hot-air balloon, Brody measures a 39° angle of depression to a landmark that's 532 feet away, measuring horizontally.
The angle of depression = 39°
The base = 532
We need to find the vertical distance consider perpendicular.

Therefore, the balloon's vertical distance above the ground is 430.80 feet.

Answer:
angels on a triangle = 180°
so you add 75 and 50 which gives you 125 then u take away that by 180 to find x (Just the process)
and that's your answer
Answer: THe equation C²=36 can have both -6 and 6 as possible values since -6 squared is 36 and so is 6 squared
Answer:
B) -3
Step-by-step explanation:
The sum of the three angles of any triangle is equal to 180 degrees.
180-50-87 = 43.
43 = x+46
x = 43-46
x = -3
