you need to see if angle EGF is a right angle so you need to determine if triangle EGF is a right triangle

4. jim_thompson5910

how do we do that?

5. janessia

hmmmm pathagorean therom?

6. jim_thompson5910

yep

7. janessia

or wait no not tht im stupid sorry lol

8. jim_thompson5910

if you can show that 17^2 + 26^2 = 30^2 is true, then it is a right triangle

9. janessia

oh u can use that?

10. jim_thompson5910

no it's correct

11. jim_thompson5910

yes

12. jim_thompson5910

it's really the converse, but who cares lol

13. janessia

yayy hold on

14. janessia

its not a right angle

15. jim_thompson5910

good because 17^2 + 26^2 = 30^2 turns into 965 = 900 which is FALSE

16. jim_thompson5910

so FG is NOT a tangent

17. janessia

ayyyeeee!!! lol im gettin it! i wish u could have been here to help me through the rest of the geometry cuz i failed it lol

18. jim_thompson5910

well you're doing great now, so that's good

19. janessia

hay im bout to post another question i need help with i think i know how to solve it but im not sure
