Do you need to find "x"?

3. leroysgurl15

yeah

5. GoldPhenoix

Yes, no, maybe?

6. leroysgurl15

yes its 90

7. GoldPhenoix

Good! Do you know how many degree there is in a straight angle?

8. leroysgurl15

180

9. GoldPhenoix

Good job! Now you can set up an equation. |dw:1380240985189:dw| Does the equation make sense?

10. leroysgurl15

kinda

11. GoldPhenoix

Alright, I'll explain it in detail at the end. Anyway, combine like terms. 90 + (-10) = ? 4x + x = ?

12. leroysgurl15

so 90+-10=80 5x

13. GoldPhenoix

Good! |dw:1380241194913:dw| Do you know what to do next?

14. leroysgurl15

subtract 80 from 180 which would be 5x=100 x=20

15. GoldPhenoix

Good job. So x = 20. I hoep this help!

16. GoldPhenoix

hope*

17. GoldPhenoix

Anyway, the reason why the equation make sense is because if you plug x into the angles: |dw:1380241423965:dw|
