The temp. rose by 17 degrees and then fell by 17 degrees. This means that the net change in temp over the course of the day was zero.
Answer:
13º
Step-by-step explanation:
We know a straight line makes 180, so the one opposite 63 is (180-63) which is 117.
We know the interior angles in a triangle make 180. We know two angles 50 and 117 and 50+117=167. 180-167=13.
56 miles : 1 hour
/2. /2
28 miles : 30 minutes
56+28. 1h+30m
84 miles : 1 hour 30 minutes
84 is the answer
