Answer:
The width (in our case it is the height) of the rectangle equals 17 miles
Step-by-step explanation:
In order to solve this, we need to know the following...
Area of a rectangle = Length x Width
(in our case based on what you said length is the base and width is the height)
Now we just change the formula to our needs and get that...
Width = Area of the rectangle / Length
And so we get...
Width = Area of the rectangle / Length
Width = 226.1 / 13.3
Width = 17 miles
To solve the equation:

Therefore, the answer is u=19.

First, that looks like Pearson and if it is, I'm so sorry for you.
Secondly, I think this answer is correct.
180 - 130 = 50°
opposite sides add up to 180
