I have a trig test that I know absolutely nothing for... I'm in bad need of math-charity!!
Part I
so questions 5-7 have the following:
GIVEN: tan A= -3/53π/2sin B= -1/4πcot C= 1/2π
5.) sin (A+B)
6.) tan c/2
7.) sin 2B
thenn...
Part II
8.) tan 7π/8 (half angle)
9.) sin 285 (sum)
10.) cos 5π/12 (difference)
My friend copied the problems, so I believe we have to use the trig identities to solve this(??) I seriously have no clue what I'm doing...... I was sick for the majority of the time she taught these.
THANK YOU for any help regarding these!!!!!!!!!!

GIVEN: tan A= -3/53π/2sin B= -1/4πcot C= 1/2π is indecipherable.

A) 35 through fact a hundred% is all or an entire B)0.35 C)80x9=720 so like a million/9 of 720 is 80 D)70x8=560 so approximately 0.12 of 560 is 70 E)840 and the entire quantity of 8th graders is a million,050 F)50 s x 40 =2000 so 200cmx40= 8000 solid success!!!
