In this question you have to take advantage of corresponding parts. You can find the angle beside the 65 degree angle by doing 180-65=115. Using your understanding of corresponding parts you can now conclude that 55+x=115. Now you just do the algebra and you get x=60
Answer: 190 minutes because if you divide 76 by 8 you get 9.5 which would be 9.5 minutes every mile so then since every mile is 9.5 minuets you multiply that by 20 and get 190 so it would be garret rode his bike 20 miles in 190 minutes
