WebStep 1: Use trigonometric formulas. Given: sin A - B = 1 10 and cos A + B = 2 29. We know that, sin θ = 1 - cos 2 θ. We know that, cos θ = 1 - sin 2 θ. Step 2: Find the value of the tangent of the sum and the difference of A and B. Since, cos A + B = 2 29 and sin A + B = 5 29. Since, sin A - B = 1 10 and cos A - B = 3 10.
