are you familiar with the law of sines?

OpenStudy (16shuston):

to solve for c just use the pythagorean theorem

OpenStudy (anonymous):

@jim_thompson5910 Yes, wow I JUST REALIZED I CAN USE IT. Thank you Lol!

jimthompson5910 (jim_thompson5910):

you're welcome

OpenStudy (cookielate):

a2+b2=c2 50+3=c2 50x50= 2500 9 2509=c2 c=/2509 square root <<< c=50.0899191455

OpenStudy (cookielate):

Does that help

jimthompson5910 (jim_thompson5910):

cookielate, the pythagorean theorem only works with right triangles. We don't know for sure if this is a right triangle or not.

OpenStudy (cookielate):

I know what it is a Acute triangle

@jim_thompson5910 actually I'm still a bit confused. I know how to solve when I receive 2 angles, but I don't know how to find the second angle.

HanAkoSolo (jamierox4ev3r):

Use the two sides that you are given to find the missing side and angles

OpenStudy (anonymous):

By using what? @Jamierox4ev3r law of cosine?

OpenStudy (anonymous):

Or this: sin R / r = sin Q / q
