Simplify the equation they gave you: 99 = 1/2*(2h + 4)*h; first multiply

99 = (h + 2)*h

99 = h² + 2h; subtract h² + 2h from both sides

99 - h² - 2h = 0; rearrange

-h² - 2h + 99 = 0; factor

(-h + 9)(h + 11) = 0; set each factor equal to 0

-h + 9 = 0 → h = 9 h + 11 = 0 → h = -11

The value of h has to be positive so lets go with 9. Plug it ito the equation to make sure.

99 = 1/2*(2(9) + 4)*9

99 = 1/2*22*9

99 = 99; that means that the answer was right → 9 is the height

I hope this helps you!

A bird (B) is spotted flying 6,000 feet from a tower (T)). An observer (O) spots the top of the tower (T) at a distance of 9,000

Nina [5.8K]

Answer:

The angle will be "48.7°".

Step-by-step explanation:

In ΔTBO, the given values are:

TB = 6,000 feet

BO = 9,000 feet

Now,

To find the angle,

⇒ $Cos \ B =\frac{TB}{BO}$

On putting the estimated values, we get

⇒ $Cos \ x=\frac{6000}{9000}$

⇒ $Cos \ x=0.66$

⇒ $x=Cos^{-1} \ 0.66$

⇒ $x=48.7^{\circ}$
