Wait but dont i have to find the length of AC first?
I found the length of the side during the process. and yes. that is correct... as I found out. Is it one of your options? - RAM231's sister
This isn't a multiple choice question.
But I know that the answers are AC=47 and angle A=17 degrees
I just don't know how to get to them
Its RAM231 again... My sister left... she is doing homework so yeah lol. But as she put it in her calculator, she got exactly what you got. she used the pythagorean theorem to get the measurement of side AC. if that makes sense
can you ask her how she got angle A?
she had to use the inverse cos to find the angle.
what's the inverse cos, again? I forgot how to do it
this may help
Refer to the Mathematica solution calculation, attached.
