1. \(cos56^{\circ} = 0.55\)<br />2. \(tan84^{\circ} = 9.66\)<br />3. \(sin36^{\circ} = 0.59\)
Explicação
## Step 1<br />The problem asks us to evaluate three trigonometric expressions: \(cos56^{\circ}\), \(tan84^{\circ}\), and \(sin36^{\circ}\). We will use the ALEKS calculator to find the values of these expressions.<br /><br />## Step 2<br />The cosine function, denoted as \(cos\), gives the ratio of the adjacent side to the hypotenuse in a right-angled triangle. For the expression \(cos56^{\circ}\), we input \(cos56\) into the ALEKS calculator.<br /><br />## Step 3<br />The tangent function, denoted as \(tan\), gives the ratio of the opposite side to the adjacent side in a right-angled triangle. For the expression \(tan84^{\circ}\), we input \(tan84\) into the ALEKS calculator.<br /><br />## Step 4<br />The sine function, denoted as \(sin\), gives the ratio of the opposite side to the hypotenuse in a right-angled triangle. For the expression \(sin36^{\circ}\), we input \(sin36\) into the ALEKS calculator.<br /><br />## Step 5<br />After calculating these values, we round each to the nearest hundredth as instructed.
