summer campers John and Ryan are trying to earn their archery merit badges. Each boy has 30 arrows and must hit the center of the target more than 10 times. John hits the center 1 time for every 3 arrows he shoots. Ryan hits the center 2 times for every 5 arrows he shoots. Which boy earns an archery merit badge?

The answer would be quadratic trinomial

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
