Since the both sides look the same it’s gonna be 12+4 which equals to 16. So it will be 16 on both sides so y= 12

Valeria drives 500 meters up a hill that makes an angle of 15 degrees with the horizontal. To the nearest tenth of a meter, what

Answer:

Approximately 485 meters

Step-by-step explanation:

We can first construct a right triangle, using the 500 m length of hill as our hypotenuse. Using the fact that the cosine of an angle is the ratio of the adjacent side to the hypotenuse, we see that

$\cos{15^\circ}=\frac{x}{500}$

where x is the horizontal distance covered. Solving for x, we find this horizontal distance to be

$x=500\cos{15^\circ}\approx500(0.97)=485$

so our answer is approximately 485 m.
