|dw:1339668880511:dw| if 16 is the base that means the two smaller lines are 8 each

5. lgbasallote Group Title

now use pythagorean theorem to find x $x = \sqrt{15^2 + 8^2}$ $x = \sqrt{225 + 64}$ do you have a calculator? i dont

6. imilee Group Title

no i dont im sorry

7. waterineyes Group Title

x = 17..

8. lgbasallote Group Title

it seems $x = \sqrt{289}$ $x = 17$ i remembered lol

Perimeter is : 50

15. waterineyes Group Title

Sorry, lgbasallote what do you mean by why you back your answers up??

16. lgbasallote Group Title

i meant don't just give answers...back them up with solutions ;)

17. waterineyes Group Title

You are giving the solutions, so I thought I can give answers so that it becomes easy for the person who has asked the question..

18. imilee Group Title

SO the answer is 50...... ok all you guys had to say is what i needed to doooo..... 17+17+16. Thank for helping you two :)

19. lgbasallote Group Title

for future note i think it's best if the askers get the answers by themselves ;) answers usually distract them from the solution

20. lgbasallote Group Title

@imilee how 17 was got is pretty important too ;)

21. waterineyes Group Title
