## marcoduuuh 2 years ago A right triangle has a hypotenuse of length 10 and a leg of length 7. What is the area of the triangle?

1. marcoduuuh

a=35?

2. ash2326

|dw:1358830749694:dw| Find the missing side

3. ash2326

@marcoduuuh Are you trying?

4. marcoduuuh

yes!

5. ash2326

Find the side then use the area formula, $\frac 1 2 \times base\times \ height$

6. godorovg

hey just an idea here take half of seven and than half of 10 and times them together

7. marcoduuuh

I got 35?

8. godorovg

1/2 of 7 is 3.5 and half of 10 is 5 so what is the answer?

9. ash2326

|dw:1358831111900:dw| You need to find the height first, formula doesn't involve hypotenuse's length

10. marcoduuuh

17.5!

11. ash2326

@marcoduuuh Can you use Pythagoras to find height?

12. godorovg

better use a2+b2=c2 may be that would work here

13. marcoduuuh

that's Pythagoras

14. godorovg

yes

15. godorovg

hey ash am I missing something here??

16. marcoduuuh

10^2+7^2= 149. sqrt of 149 is: 12.2065556

17. godorovg

does this problem have answer choices or anything??

18. marcoduuuh

Nope, it doesn't. ):

19. godorovg

one sec checking something here

20. marcoduuuh

ok

21. godorovg

wait I know now

22. godorovg

opp/ adj what is the function?

23. godorovg

you still there?
