Answer:

11.1 =x

Step-by-step explanation:

Since we have a right triangle, we can use trig functions

cos theta = adjacent side/ hypotenuse

cos 42 = x/15

Multiply each side by 15

15 cos 42 = x

11.14717238 =x

Rounding to the nearest tenth

11.1 =x

Rashid [163]

Answer: 800 miles

After dividing you get 800

That means that he can drive for 800 miles and still stay within  his budget
