Step 1: Recall the definition of tangent in a right triangle. The tangent of an angle θ is defined as the ratio of the length of the opposite side to the length of the adjacent side: tan(θ) = opposite / adjacent.
Step 2: Identify the sides of the triangle relative to the angle θ. From the image, the side opposite θ is 12, and the side adjacent to θ is 16.
Step 3: Substitute the values of the opposite and adjacent sides into the formula for tangent: tan(θ) = 12 / 16.
Step 4: Simplify the fraction 12 / 16 by dividing both the numerator and denominator by their greatest common divisor, which is 4. This simplifies to tan(θ) = 3 / 4.
Step 5: Verify that the simplified ratio matches one of the given options. The correct answer is tan(θ) = 3 / 4.
