Trigonometry question! find y. round to the nearest tenth!

tresset_1 [31]

Answer:

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 hypotenuse:

$\alpha=29^o,\ hypotenuse=500\ ft$

$\sin29^o\approx0.48481$

Substitute:

$\dfrac{y}{500}=0.48481$ <em>multiply both sides by 500</em>

$y=242.405\to y\approx242.4$

(1/2)x +y = 3 (equation 1)
2x +4y = 12 (equation 2)

((1/2)x +y = 3) x4
= 2x +4y = 12

2x +4y = 12
-
2x +4y = 12
= nothing

answer is B infinitely many solutions as the lines are stacked on top of another.
