So this is a right triangle so you can use sin, cosine, or tangent. for A, you have the sides opposite and hypotenuse, which means you use sin*
sin(A) = opposite / hypotenuse
sin(A) = 56 / 75
arcsin(56/75) = A
A= about 48.3
so to the nearest degree, your answer is 48
*soh cah toa (if you dont know what that is, i can explain it)
You gotta divide $6.45 and 3 together to find the answer
So the first step is to have a line segment.
Put your compass on one of the points and extend the compass to be slightly more than half. Just a bit over half.
Mark a small curvy line above your segment and on the bottom at that length.
Now pick up the compass, don't change the length of extension, and put it on the other point of your segment.
Mark above and below your segment like before so it can intersect.
draw a line through the two intersections.
I hope I answered your question.
Answer:

Step-by-step explanation:
To find the unit rate we need to divide the # of miles over the number of practices to get the # of miles ran in a single practice:
=
