So every triangle has to add up to 180° so for 11 you would have to find out 180-84-36 which would be 60 and because there is a right angle (90°) or the little square you do 90-60 and get 30 then you do 180-86-30 getting you to your final answer of 64

Tatiana [17]

Find out how much you need for one person then multiply by 18 is one way you could do this..

4 divided by 24 = 0.166666666666667 x 18 = 3 litres of lemon-lime soda.

2 divided by 24 = 0.083333333333333 x 18 = 1.5 pints of servet

6 divided by 24 = 0.25 x 18 = 4.5 cups of ice.

Hope this helps!
