A building that is 115 feet tall casts a shadow that is 190 feet long. Determine the angle at which the rays of the sun hit the ground to the nearest degree.
\[\Huge{\bf{WELCOME\ TO\ OS}}\]
|dw:1353687825684:dw|\[\tan \theta=\frac{AB}{BC}\]
It is given that |BC|=115 feet and |AB|=190 feet We have to find \[\theta=?\]
Use the formula that @ujjwal Has provided and solve for the Angle :)
@Cortney95 Do you understand,if you are not clear about anything please ask ?
Then leave it @ujjwal Until @Cortney95 returns.
I understand thank you so much :)
The answer choices are A) 31° B) 37° C) 52° D) 53° and The answer I am getting is a decimal.
@Cortney95 Please interact ......
Please round of to the nearest,if your answer is close to your options :)
Sorry had to help family with something. My decimal was1.652173913
No problem @Cortney95 ,It is better you show me your working so I can indicate where you go wrong.
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
Look \[\tan \theta=\frac{ AB }{ BC }\] and \[\theta=\tan^{-1} \ (\frac{ AB }{ BC })\]
@Cortney95 I hope now you get it :)
Welcome,What answer did you get ?
Could you help Me with another problem?
Sure please post it in another tab and tag me there :)
Im new to all of this so I will try
To do so you will have to close this question first :)
