## sunsetlove 3 years ago What is the magnitude and direction of if G(2, -2) and H(7, 6)? Answer magnitude: 9.43 units; direction 32.01° magnitude: 9.43 units: direction: 57.99° magnitude: 6.4 units: direction: 32.01° magnitude: 6.4 units; direction: 57.99°

1. sunsetlove

my bro is here to help me

2. Tyler1992

Distance formula gives you the magnitude

3. sunsetlove

ok

4. Tyler1992

So $\sqrt{(7-2)^2 + (6-(-2))^2}$

5. Tyler1992

$\sqrt{5^2 + 8^2}$

6. amitlpu91

& for direction use tan(angle )

7. sunsetlove

25 + 64

8. Tyler1992

good

9. Tyler1992

so $\sqrt{89}$

10. Tyler1992

Im not sure what that number is. I cant find my calculator.

11. Tyler1992

Its 9.something

12. sunsetlove

its 9.43

13. Tyler1992

Ok good.

14. sunsetlove

15. Tyler1992

You need to measure this angle: |dw:1327169304502:dw|

20. GT

Tan(x) = 8/5 Find x.

21. Tyler1992

^ ahh ok

22. amitlpu91

or u can simply apply tan(angle) as ---|dw:1327169661006:dw|

23. amitlpu91

so its simply............|dw:1327169739384:dw|
