PROBLEM
If sin(theta) = 3/5 and cos(theta) = 4/5, find tan(theta).
If sin(theta) = 3/5 and cos(theta) = 4/5, find tan(theta).
A.
3/5
B.✓ Correct
3/4
C.
5/4
D.
4/3
Detailed Explanation
Choice B is the best answer. tan = sin/cos = (3/5) / (4/5) = 3/4
Why others are wrong:
A: 3/5 is incorrect because it does not satisfy the equation.
C: 5/4 is incorrect because it does not satisfy the equation.
D: 4/3 is incorrect because it does not satisfy the equation.
