[AI-generated answer — Bot GPT 3.5]

Solving the equation:

7.5 cos(-1.93) - 2.2 = 2(0.1)
7.5 * cos(-1.93) - 2.2 = 0.2

Step 1: Evaluate the cosine of -1.93.
cos(-1.93) ≈ 0.5728

Step 2: Substitute the value of cos(-1.93) back into the equation.
7.5 * 0.5728 - 2.2 = 0.2
4.296 - 2.2 = 0.2
2.096 = 0.2

Therefore, the equation is not true.
