If sin A=4/5,find the value of 5cos A + 3tan A​

Sagot :

Answer:

steps below

Step-by-step explanation:

If A in first quadrant: sin A = 4/5,  cos A = 3/5,  tan A = 4/3

5cos A + 3tan A​ = 5 * 3/5 + 3 * 4/3 = 3+4 = 7

If A in second quadrant: sin A = 4/5,  cos A = - 3/5,  tan A = - 4/3

5cos A + 3tan A​ = 5 * -3/5 + 3 * -4/3 = -3 + -4 = -7
