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

hba · Answer

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

hba · Answer

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

hba · Answer

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

ujjwal · Answer

anonymous · Answer

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

hba · Answer

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

hba · Answer

@Cortney95 You there ?

anonymous · Answer

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

hba · Answer

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