Hey there! :D
Pay attention to the given angles.
We know that a circle is equal to 360 degrees.
We know two angles, and the other 2 are the same measure.
170+44= 214
Subtract that from 360, since that is what the circle equals.
360-214= 146
Divide that by two, since there are 2 equal angles left.
146/2= 73
<DOB= 73 degrees.
You were correct, so good work!
I hope this helps!

W=wind
p + w=158...p=158-w
p-w=112...p=112+w
SO 158-w=112+w
46=2w
23=w
SO in conclusion you have the correct answer of wind being 23km/h while the plane is going 135 km/h
HOPE THIS HELPS!
Usually when you do expressions involving subtraction you can do Keep, Change ,Change
That means you keep the sign of the first number and change the other two signs.
It is best you rewrite the expression to addition because a lot of people don't do well with subtracting .
