Answer:

Step-by-step explanation:

Use the CAH from SOHCAHTOA.

CAH is cosΘ = $\frac{Adjacent}{Hypotenuse}$

Substitute the given values into the above formula.

The adjacent side of ∠D measures 8, and the hypotenuse (the longest side of the right triangle) measures 16.

cosΘ = $\frac{Adjacent}{Hypotenuse}$

cos D = $\frac{8}{16}$

D = $cos^{-1}$ ( $\frac{1}{2}$ )

D = 60°

Therefore, the m∠D = 60°

Charlie runs at a speed of 3 yards per second . About how many miles per hour does Charlie run?

Ok so this can get tricky, it is basically just asking for you to perform many unit conversions. I'll try to simplify it for you here while still maintaining the explanation. If you have any questions about this process feel free to message me.

3 yards = ____ miles (conversion factor is 1760 because there are 1760 yards in a mile)

3/1760 = 0.017 miles,

Now we just need to convert seconds to hours.

1 second is how many mins, then how many mins in an hour?

360 seconds in an hour.

Ok now we just need to combine these two pieces of info,
0.017/360 = 4.72222 miles per hour. Thus 4.72 is the answer.
