Male teacher-n
Female teacher-n+23
N+n+23=107
2n+23=107
2n= 84
N=42
Male teacher-42
Female teacher-42+23=65
65/107 teacher are female
X = 68
Since the angle opposite of it is a right angle, we know that 22 + x has to equal 90 also.
So just take 90 - 22 = 68 degrees
4(1/2x7)=12 <=> x28/2=12
x=12*2/28=24/28=12/14=6/7
I think the first part is 466
