Solve for e. (-7) = e/3 + 14

raketka [301]

<span>(-7) = e/3 + 14

Subtract 14 on both sides

-7 - 14 = e/3 + 14 - 14

-21 = e/3

Multiply by 3 on both sides

-21 * 3 = e/3 * 3

-63 = e</span>

Answer:

The length of shadow is 69 foot.

Step-by-step explanation:

We are given a shadow of lighthouse.

Length of top of lighthouse to end of shadow is 90 ft.

Angle make at top of lighthouse is 50°

Distance from foot of lighthouse to end of shadow is x ft.

we need to find the length of shadow i,e x ft

Using trigonometry ration:

$\sin\theta=\dfrac{P}{H}$

$\sin50^\circ=\dfrac{x}{90}$

$x=90\times 0.766$

$x=68.94\approx 69\text{ ft}$

Hence, The length of shadow is 69 foot.
