|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 :)

Then leave it @ujjwal Until @Cortney95 returns.

9. Cortney95

I understand thank you so much :)

10. hba

Your'e welcome.

11. Cortney95

The answer choices are A) 31° B) 37° C) 52° D) 53° and The answer I am getting is a decimal.

12. hba

What do you get ?

13. hba

@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

I do thx

24. hba

Welcome,What answer did you get ?

25. Cortney95

d
