The answer to the question is 12
we can say that there are 15 male teachers for every 35 female teacher

Angle 3:
62+47=109
All angles in a triangle add to 180 degrees, so 180-109= 71 degrees
Angle 2:
Angles in a straight line always add to 180 degrees too,
so 180-62= 118 degrees
Angle 1:
Again, angles in a triangle add to 180,
so 180-22-118= 40 degrees
Angle 1: 40
Angle 2: 118
Angle 3: 71
Hope that helps :)
Answer:
-4 degrees
Step-by-step explanation:
Starting at 2 degrees, you need to subract 6 since 200 km= 6 degrees and it decreases.
