Work Step by Step

Step 1: First, we have to convert degrees and minutes to decimal degrees: $42^{\circ}18'=42\frac{18}{60}^{\circ}=42.3^{\circ}$ Step 2: Next, after ensuring that the calculator is in degree mode, we type $\sin42.3^{\circ}$ into the calculator. Step 3: Solving, we find that: $\sin42.3^{\circ}\approx0.67301251$
