Question

Help needed please!!!

Answer 1

cosine A = adjacent / hypotenuse
cosine A = 10/12 = 5/6
cosine A = .8333333333333
arc cosine (.8333333333) = 33.557 Degrees
Angle A = 33.557 Degrees

sine C = opp / hyp
sine C = 10/12
sine C = .83333333333333
Arc Sine of .83333333333333 = 56.443 Degrees

Answer 2

you're gonna use the inverse of sine cosine and tangent so for A....
you know the adjacent and the hyponuse so ur gonna use inverse of cosine which would be like inverse of cosine YOU KNOW WHAT IM GONNA SEND MY WORK INSTEAD....NVM THEY GOT IT
