Help I will give 10 points

x = 10

5x = 50

2x = 20

Step-by-step explanation:

This is a triangle, so all the angles will equal 180, so you can set up the equation like so:

110 + 5x + 2x = 180

COmbine like terms:

110 + 7x = 180

Subtract 110 from each side:

7x = 70

divide each side by 7:

x=10

Substitute to find the values of the angles:

5x

5 ( 10 )

50

2x

2 ( 10 )

20

a = 3.14

b = 18

c = 18/5 or 3.6 or 3 3/5

step-by-step explanation:

sinn is the total amount of students now and m were the students before, you subtract them both (n-m) and divide that by m. then, since to get a percentage from a fraction you have to multiply by 100, your answer should look like this: n-m/m*100
