## autumnpoteet 2 years ago In ΔPQR, sin P = 0.3, sin R = 0.4 and r = 10. Find the length of p.

1. AonZ

is this a right angled triangle?

2. autumnpoteet

No

3. AonZ

do you have a diagram or ur trouble is drawing one?

5. autumnpoteet

Not a full on triangle , it slants to the right.

7. autumnpoteet

how do i do that...

8. Mertsj

Substitute the know values, cross multiply and solve.

9. Mertsj

You are given sin P, sin R and r

10. autumnpoteet

so i have 0.3/p = sinP/10

11. Mertsj

sinP is given to be .3 Replace sin P with .3

12. autumnpoteet

i did.|dw:1370195180316:dw|

13. Mertsj

14. Mertsj

Cross multiply and solve.

15. autumnpoteet

so 10x0.3= 3 what does 0.4 x p = 0.4p ?

16. Mertsj

yes

17. autumnpoteet

great !

18. autumnpoteet

so for the answer do i just put 0.4p?

19. Mertsj

To solve this equation: 3=.4p Divide both sides by .4

20. autumnpoteet

okay. 0.4/3 = 0.13 3/0.4 = 0.75

21. autumnpoteet

0.4/0.4 = 1

22. Mertsj

23. autumnpoteet

7.5

24. Mertsj

yes
