Answer:
Step-by-step explanation:
A will third quadrant
cosA=-3/5 (A in third quadrant)
A=53degrees(cosA=3/5,A=53degrees)
sin53+tan53
(sin is negative in third quadrant)
(tan positive in third quadrant)
-4/5(sin53=4/5,in third quadrant negative =-4/5)
tan53=4/3
-4/5+4/3
lcm of 5,3 is 15
-12+20/15
8/15 is answer
