Explanation: To get the value of the tan of the difference between the angles, we will use the formula attached in the image. Now, we are given that: tanθ = 3/5 tanβ =1/2 Substitute with the givens in the formula to get tan(θ - β) as follows: tan(θ - β) = [(3/5)-(1/2)] / [1 + (3/5)(1/2)] tan(θ - β) = (1/10) / (13/10) tan(θ - β) = 1/13
