Answer:

1) 35

2) 125

Step-by-step explanation:

angle adc = x

x+ 90 + 20 = 180 (triangke sum property)\

x = 180 - 110 = 70

angle bdc = 70/ 2 = 35 ( the median cuts the angle into 2)

2) cbd = x = 125

x + c + bdc = 180

x + 35 + 20 = 180

x = 180 - 55 = 125

I hope im right!!!

This inequality says what the sentence says!

now, the number of teachers must be:
x≥2*(y/25)
(two times the number of groups of students of 25!)

so those two inequalities, taken together will be the answer!
