A blimp can be seen flying at an altitude of 5500 feet above a motor speedway during a race. The slanted distance directly to th
Vladimir [108]

Answer:

The expression of h as function of x is   h = \sqrt{(d + 5500) (d - 5500)}

Step-by-step explanation:

Given as :

The distance of blimp  (AB) = 5500 feet

The slanted distance to the pagoda (BC) = d feet

The horizontal distance (AC) = h

Let the angle made between slanted distance and horizontal distance be Ф

So , cos Ф = \frac{AC}{BC} = \frac{h}{d}

And sin Ф =  \frac{AB}{BC} = \frac{5500}{d}

∵, cos²Ф = 1 - sin²Ф

So, (\frac{h}{d})^{2} = 1 - (\frac{5500}{d})^{2}

Or, (\frac{h}{d})^{2} = (\frac{d^{2}- 5500^{2}}{d^{2}})

Or,                                     h² = d² - 5500²

∴                                        h = \sqrt{d^{2}- 5500^{2}}

Or,                                     h = \sqrt{(d + 5500) (d - 5500)}

Hence The expression of h as function of x is   h = \sqrt{(d + 5500) (d - 5500)}     Answer

PLEASE HELP ASAP ! a skyscraper casts a shadow 200 feet long is the angle of elevation of the sun is 42 the height is
levacccp [35]

Answer:

A) 180.08 feet

Step-by-step explanation:

The diagram depicting the situation is shown in the attachment.

From the diagram the height is f ft.

The side we are trying to find is opposite to the given angle which is 42\degree

We use the tangent ratio to obtain;

\tan 42\degree=\frac{f}{200}

We solve for f to get:

f=200\tan 42\degree

f=180.08ft
