Solution

The correct option is B
$82 °$

Angle sum property: Sum of all the interior angles of a triangle is $180 °$
Lets assume the third angle is $x °$
$\begin{array}{rcl} x ° + 60 ° + 38 ° & = & 180 ° \\ x ° + 98 ° & = & 180 ° \\ x ° & = & 180 ° - 98 ° \\ x ° & = & 82 ° \end{array}$
Hence, the measure of the third angle is $82 °$
