The rule for a rotation by 180° about the origin is (x,y) -->(−x,−y)
So A(-3, 2) to A'(3, -2)
Answer:
A'(3, -2)
The answer is 63 degrees.
His elevation is higher than 1600, where there is less oxygen and, air which technically contains oxygen, and the fact that elevation means going “up”.

You simplify it: 40v=18
v= 9/20
