Answer: tanA=3/4

Step-by-step explanation: If  cosA=4/5 then

sinA=√(1−cos2A)  {Because sin^2A+cos^2A=1}

=>sinA=√(1−16/25)

=>sinA=√(9/25)

=>sinA=3/5

Now as  tanA=sinA/cosA

=>tanA=3/5×5/4  {Because 1/cosA=5/4}

=>tanA=3/4

Answer:

D.

Step-by-step explanation:

In order to eliminate, the numbers must eliminate. If the second equation is multiplied by 3, then the 3 and the -3 can be eliminated. Since it is multiple choice, we can plug in x = 12 and y = 10 to see if they are correct. 12 + 30 = 42 and 24 - 10 = 14, so D is correct.
