PLEASE HELP!!!

Answer:

See below

Step-by-step explanation:

4(x + 5) = 9x + 4x − 34

4x + 20 = 9x + 4x − 34 [Distributive]

4x + 20 = 13x − 34 {Combine Like Terms]

4x - 13x + 20 = 13x - 13x − 34 [Subtractive: -13x both sides]

-5x + 20 = - 34 [Combine Like Terms]

-5x + 20 - 20 = -34 - 20 [Subtractive: - 20 both sides]

-5x = -54 [Combine Like Terms]

x = -54/-5 [Division Property: divide both sides by -5]

x = - 10 4/5

AnnZ [28]

Answer:

The height of the hot air balloon is 1514.54 feet approximately.

Step-by-step explanation:

Consider the provided information.

The angle of elevation from the top of a 95-foot tall building to a hot air balloon in the sky is 76. If the horizontal distance between the building and the hot air balloon is 354 feet, find the height of the hot air balloon

The figure is shown below:

Let the height of the balloon is AD, the height of the building is BC.

Draw a line BE parallel to CD.

Therefore, AD=x+95, BC=95 and BE=CD=354 ft

Now in triangle $ABE$ .
