Question

Someone please help! find x round to the nearest tenth! trigonometry!​

Answer 1

Answer:

x = 745.5 ft

Step-by-step explanation:

Look at the picture.

Use sine:

$sine=\dfrac{opposite}{hypotenuse}$

We have a measure of the angle and length of the opposite:

$\alpha=28^o,\ opposite=350\ ft$

$\sin28^o\approx0.4695$

Substitute:

$\dfrac{350}{x}=0.4695$

$\dfrac{350}{x}=\dfrac{4695}{10000}$            cross multiply

$4695x=3500000$           divide both sides by 4695

$x=\dfrac{3500000}{4695}\to x\approx745.5$
