What is the answer?​

Answer:

x = 20 but see below.

Step-by-step explanation:

Remark.

This is not well enough marked to know whether D = A or whether you have to do some algebra to find the relationship between A and D. So I will assume A = D and then I'll solve it so you have to manipulate A and D.

A = D

3x - 10 = 2x + 10                     Add 10 to both sides

3x - 10 + 10 = 2x + 10 + 10     Cancel

3x = 2x + 20                           Subtract 2x from both sides

3x-2x=2x-2x + 20

x = 20

A = E

If A = E then to find x you have to add 3 angles together.

E + D + 45 = 180                  Add the three angles of the triangle

E + D = 180 - 45                  Subtract  45 from both sides

E + D = 135                          Substitute for D and E

3x - 10 + 2x + 10 = 135        Combine like terms

5x = 135                              Divide by 5

x = 135 / 5

x = 27

Answer

I'd go with the first one.

Girls going = (3/5) * 20 = 12

Girls not going = 20 - 12 = 8
