Answer:
W = 87 degrees
Step-by-step explanation:
First we can rearrange the question so that W is isolated on the left side, which we do by dividing both sides by tan:
tanW/tan = 19.0811/tan
W = 19.0811/tan
Now we can use the inverse tan function on the calculator () to calculate it:
W = 19.0811 x
W = 87 degrees
