6. Nnesha

is it a right triangle ?

7. anonymous

@Nnesha yes

8. Nnesha

alright Pythagorean theorem $\huge\rm a^2 +b^2 =c^2$ plug in values and solve for missing side remember c is the longest side of right triangle which is hypotenuse

9. anonymous

@Nnesha so 15^2+b^2=17^2

10. Nnesha

yes right solve for b

11. anonymous

@Nnesha so then 225+b^2=289

12. Nnesha

yep

13. anonymous

@Nnesha then do I do 289-225?

14. Nnesha

yep

15. anonymous

@Nnesha I got 64 but 64 isn't one of my answer options...

16. Nnesha

yep b^2 = 64 you need b

17. anonymous

@Nnesha sorry what do I do next? I haven't done this in a while..

18. Nnesha

so you have to take square root both sides to cancel out square of b
