Question

If cosA = -3/5 and A is not in 2 nd quadrant , then find the value of SinA + tanA

Answer 1

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
