Explanation:

Recall that

when dealing with the unit circle.

The x coordinate of the point shown is x = 5/13, which tells us that cos(A) = 5/13.

We can also see that y = 12/13 which leads to sin(A) = 12/13.

Divide sine over cosine to get tangent

tan(A) = sin(A)/cos(A)

tan(A) = sin(A) ÷ cos(A)

tan(A) = (12/13) ÷ (5/13)

tan(A) = (12/13) * (13/5)

tan(A) = 12/5

In the last step, the '13's cancel out.
