(A) 4(x+5). Distribute the 4 (multiply both numbers by 4) and you get

4x+4*5

4x+20

(B) 70 km/h * y hours is 70y km, because you traveled 70 km every hour, so it's 70 times y.

The sun is directly overhead. The shadow of the balloon falls
Mariana [72]

The height of the ballon is 34 feet 2 inches.

To be able to solve this question, we need to understand the concept of angle of elevation.

<h3>What is the angle of elevation?</h3>

An angle of elevation is the angle formed between the horizontal plane (adjacent line) to the line of sight(elevation) from the viewer's eye to the object located in the space.

  • The diagrammatic expression for the question given can be seen in the image attached below.

From the image below, we can determine the height of the ballon by taking the tangential trigonometric function.

\mathbf{tan \theta = \dfrac{opposite}{adjacent}}

\mathbf{tan \ 67= \dfrac{x}{14 ft \ 3 in }}

Let's first convert 14 ft 6 in to ft, by doing so, we get 14.5 ft

\mathbf{tan \ 67= \dfrac{x}{14.5\ ft }}

x = tan 67 (14.5 ft)

x = 2.356(14.5 ft)

x =34.162 ft

To ft and inches, we have:

x = 34 ft 2 inches

Lorico [155]
She is not correct because mixing the legs won't affect but mixing them with the hypotenuse would affect a lot. <span />
