Question

http://prntscr.com/arl32u
I'm trying to use my calculator to solve
c(sin55)=68(sin81)/sin55 using the EE thing I used last time, but now when I press EE and press 8 sin then try to multiply by 68 it gives me zero.

Answer 1

My main question is this however

I'd like to be guided through this, but I wanted to bring up the calculator problem since I just did the calculator thing with you @jim_thompson5910

Answer 2

I press EE, then 8, then sin, then multiply by 68, and it gives me zero

Answer 3

before you set up any equations or formulas, you should draw out the triangle if it's not already drawn for you

Answer 4

I did. : )

I'll show it to you.

Answer 6

good, angle C is 81 degrees since

55+44+81 = 180

Answer 7

I used the all triangles add up to 180 to find the measure of angle C, then used that to setup an euation 81sin/c=55sin/68 and then simplified that to c(sin55)=68(sin81)/sin55

Answer 8

one thing to remember: angle B is opposite side b

the angle letter is opposite the side letter
angles are usually in caps, sides in lower case
