Answer

Final Answer: The measure of angle $W$ is $\boxed{117}$ degrees.

Steps

Step 1 ：In a parallelogram, opposite angles are equal. Therefore, the measure of angle W is equal to the measure of angle U.

Step 2 ：We can set up an equation to solve for p, using the given expressions for W and U: $2p + 81 = p + 99$.

Step 3 ：Solving this equation gives $p = 18$.

Step 4 ：Substituting $p = 18$ into the equation for W gives $W = 2*18 + 81 = 117$.

Step 5 ：Final Answer: The measure of angle $W$ is $\boxed{117}$ degrees.
