First let's find y. We know the sum of angles equals 180, so if we add the angles of ABC, we'd get 180.
30+y+80+y=180
110+2y=180
2y=70
y=35
You could solve x ,but the only response with y=35 is c. But to solve for x, you'd ad 35 35 and xwhich would equal 180.
35+35+x=180
70+x=180
x=110
SO from what I did was...
Since 24 x 3 = 72 , I did the same to 16.
16 x 3 = 48
But because instead of their being 3 teachers there is 1... What I did is just was to divide 48 / 2 which gave me the answer of 24...
So what I think the answer is...
There are 72 boys, 24 girls, and 1 teacher...
Unless I am just dumb and it would be 48 girls, but I think I did it right.
I hope I was able to help out.

Answer:
The lengths of the sides can be 10, 30 and 31. This would be a scalene triangle.
Step-by-step explanation:
In order to determine if it can create a triangle, we simple need to make sure that the value of one side is not greater than the other two added together. In this case, 10+30 > 31, which means it can be a triangle.
A triangle with no matching sides is called a scalene triangle. Therefore, we know it is a scalene triangle.
