For each problem below, the magnitudes of the horizontal and vertical vector components, \(\mathbf{V}_{x}\) and \(\mathbf{V}_{y}\), of vector \(\mathbf{V}\) are given. In each case find the magnitude of \(\mathbf{V}\). $$ \left|\mathbf{V}_{x}\right|=35.0,\left|\mathbf{V}_{y}\right|=26.0 $$

Use the Cofunction Theorem to fill in the blanks so that each expression becomes a true statement. \(\sin 10^{\circ}=\cos\)

Refer to right triangle \(A B C\) with \(C=90^{\circ}\). In each case, solve for all the missing parts using the given information. (In Problems 35 through 38 , write your angles in decimal degrees.) \(A=32.6^{\circ}, a=43.4\) inches

Change each of the following to decimal degrees. If rounding is necessary, round to the nearest hundredth of a degree. $$ 45^{\circ} 12^{\prime} $$
