Answer

$0.5148$

Work Step by Step

Step 1: We ensure that the calculator is in radian mode. Step 2: $\sin s=0.4924$ can be written as $s=\sin^{-1} 0.4924$ Step 3: Using the inverse cosine function in the calculator, we type $\sin^{-1} 0.4924$ into the calculator and solve. Step 4: $s=\sin^{-1} 0.4924\approx0.5148$
