PROBLEM
If sin(theta) = 6/10 and cos(theta) = 8/10, find tan(theta).
If sin(theta) = 6/10 and cos(theta) = 8/10, find tan(theta).
A.
8/6
B.
6/10
C.✓ Correct
6/8
D.
10/8
Detailed Explanation
Choice C is the best answer. tan = sin/cos = (6/10) / (8/10) = 6/8
Why others are wrong:
A: 8/6 is incorrect because it does not satisfy the equation.
B: 6/10 is incorrect because it does not satisfy the equation.
D: 10/8 is incorrect because it does not satisfy the equation.
