## anonymous 2 years ago help? 2 questions c: medal!

1. anonymous

3. What is the value of x to the nearest tenth? a.18 b.19 c.71 d.72

2. Mertsj

In relation to the angle x, what sides do you know: hypotenuse, adjacent, opposite. Choose.

3. anonymous

hypotenuse?

4. Mertsj

Do you understand that the hypotenuse is always the longest sides in a right triangle and that it is opposite the right angle?

6. anonymous

yes I understand

7. Mertsj

So I repeat my original question: In relation to the angle x, what two sides do you know?

8. Mertsj

dang, buddy, the triangle only has 3 sides. If it's not the hypotenuse, what is left?

9. anonymous

I know sorry my screen froze I guess adjacent and opposite

10. Mertsj

Which is the adjacent side: 11 or 33? Remember adjacent means "next to"

11. anonymous

33

12. Mertsj

Now, you know the adjacent side and the opposite side, what trig function does that make you think of?

13. anonymous

tan right?

14. Mertsj

yes

15. Mertsj

$\tan x=\frac{opp}{adj}$

16. Mertsj

Fill in the sides and solve the equation for x

17. anonymous

I got 0.00581 ? ...

18. Mertsj

What did you get for the tangent?

19. anonymous

that's what I got I put tan 11/33

20. Mertsj

$\tan x=\frac{11}{33}=\frac{1}{3}=.3333333...$

21. anonymous

how did you get the last part?

22. Mertsj

What do you think 1 divided by 3 is?

23. anonymous

and the answers are a.18 b.19 c.71 d.72 /:

24. anonymous

ohhh ok nvm >_<

25. Mertsj

So type .33333333 into your calculator and then push the inverse tangent button

26. Mertsj

Or, depending on your calculator push inverse tangent button and then .33333333 =

27. Mertsj

What did you get?

28. anonymous

okay im using this calculator because I don't have one and still doing that I get the same answer .. http://web2.0calc.com/

29. Mertsj

Push 2nd Then the tan button will say atan which stands for "arctangent" Then enter .3333333333 Then push =

30. anonymous

18.4 ! a

31. Mertsj

yep

32. anonymous

thank you
