the ans is in the picture with the steps
(hope it helps can i plz have brainlist :D hehe)
Step-by-step explanation:
I am probably wrong but 45 degrees? Most if not all triangles equal 180. Since we already have 90 degrees we can subtract 90 from 180 and get 90. Both of the angles on the bottom left and right look about the same size so we can divide 90 by 2 and get 45.

Answer:
15
Step-by-step explanation:
32-19 = 13 that have both
70-57= 13 that have both again from that sample
total number of people that have both : 13 + 13 = 26
11 kids don't have either one, so :
26-11 = 15
