|dw:1353687825684:dw|$\tan \theta=\frac{AB}{BC}$

4. hba

It is given that |BC|=115 feet and |AB|=190 feet We have to find $\theta=?$

5. hba

Use the formula that @ujjwal Has provided and solve for the Angle :)

6. hba

@Cortney95 Do you understand,if you are not clear about anything please ask ?

7. ujjwal

asker is absent @hba

8. hba

Then leave it @ujjwal Until @Cortney95 returns.

12. hba

What do you get ?

13. hba

@Cortney95 ?

14. hba

@Cortney95 Please interact ......

15. hba

Please round of to the nearest,if your answer is close to your options :)

16. Cortney95

Sorry had to help family with something. My decimal was1.652173913

17. hba

No problem @Cortney95 ,It is better you show me your working so I can indicate where you go wrong.

18. hba

@Cortney95 You there ?

19. Cortney95

I divided 190/150 and got that as a decimal since you said earlier that I should divide ab/bc and Ab=190 and Bc=115

20. hba

Look $\tan \theta=\frac{ AB }{ BC }$ and $\theta=\tan^{-1} \ (\frac{ AB }{ BC })$

21. Cortney95

Ohh

22. hba

@Cortney95 I hope now you get it :)

23. Cortney95
