Answer

Final Answer: The measure of the third angle is \(\boxed{31}\) degrees.

Steps

Step 1 :Given the measures of two angles of a triangle as \(38^{\circ} 30^{\prime}\) and \(110^{\circ} 5^{\prime}\).

Step 2 :Convert the given measures to decimal form. So, \(38^{\circ} 30^{\prime} = 38.5^{\circ}\) and \(110^{\circ} 5^{\prime} = 110.08333333333333^{\circ}\).

Step 3 :The sum of the angles in a triangle is always 180 degrees. So, to find the measure of the third angle, we need to subtract the sum of the given two angles from 180 degrees.

Step 4 :Calculate the measure of the third angle as \(180 - (38.5 + 110.08333333333333) = 31.41666666666667^{\circ}\).

Step 5 :However, the question asks for a whole number. Therefore, we should round the third angle to the nearest whole number.

Step 6 :Round the third angle to get \(31^{\circ}\).

Step 7 :Final Answer: The measure of the third angle is \(\boxed{31}\) degrees.
