A)\theta =58\deg 54' B)\theta =58\deg 50' C)\theta =58\deg 56' D)\theta =58\deg 48'

sin a = 12/13, a lies in quadrant I, and cos b = 7/25, b lies in quadrant 1. Find cos (a+b).

please help me understand this!!

PYTHAGOREAN THEOREM Right angle triangle: C=25 A=x B=4x . My textbook says x=6.06 but I think it's wrong, please explain how I work this out. I know the formula is...

The problem refers to an ABC triangle if B=120 degrees and C=10 degrees and c=29 find b. I did law of sines and got b= 144 but that is the wrong answer help with steps please. I did (29)/sin(10degrees)...

Confused

From trigonometry

what is the answers

please help

I'm having a really hard time understanding this! Please help!

please help! I'm very confused!

Which of the following trigonometric values are negative? I. sin(-292°) II. tan(-193°) III. cos(-207°) IV. cot 222°

a) 6 cis 0/deg ,6 cis 180\deg b) 6 cis 90/deg ,6 cis 270\deg c) 6 cis 45/deg ,6 cis 225\deg d) 6 cis 135/deg ,6 cis 315\deg
