You and a friend start biking in opposite directions from the same point. You travel 108 every 8 seconds. Your friend travels 63 feet every 6 seconds.

a) to the nearest hundredth if a mile, how far apart are you and your friend after 15 minutes?

b) after 20 minutes you take a 5-minute rest, but your friend does not. To the nearest hundredth of a mile, how far apart are you and your friend after 40 minutes?

Okay so for every triangle has three angles that always add up to 180 degrees. and to tell the difference between whether they are secure, right or obtuse is that acute: has one angle that is less than 90 degrees. right triangle means there is at least one angle that is exactly 90 degrees. and an obtuse angle has an angle that is bigger than 180 degrees. i’ll do #13 as an example: 13. 40 and 50 so if every triangle has 180 degrees 40+50= 90 degrees then180-90= 90 degrees so the third angle is 90 degrees and because this triangle has a 90 degree angle it means it is a right triangle

X= 49; x = 4step 1: foilstep 2: equal both to 0step 3: find x individually

The correct answer is 7

The answer is 60.9774
