For a candy-making competition, Tanya made 3 kinds of candies. She made 3 times as many orange candies as pineapple candies. She made 30 more lemon candies than pineapple candies. The ratio of orange candies to lemon candies was 2 to
Which equation could be used to find the number of pineapple candies Tanya made for the competition?

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
