A car begins at point A. During its trip, the car moves in a straight line until it reaches a point that is 3 miles south and 4 miles east relative to point A. The car then immediately moves to its final destination which is 2 miles south and 4 miles east relative to point C. The entire trip takes 19 minutes. 13 3 4 a. Write the transformation as a single composition. b. Let the car's final destination be point B. What is the straight line distance from the car's starting point to point B? c. Find the car's average speed throughout the entire trip in miles per hour

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
