Answer:
m=-3
Step-by-step explanation:
The rise of -7 means that there is 7 less. The fall of 7 would mean that it is also 7 less. So, yes. They are both the same thing.
The pythagorean theorem is more apt for the problem
The little square in the top left corner means it is a right angle which equals 90 degrees.
The bottom angle is given as 56.7 degrees.
The three inside angles of a triangle need to equal 180 degrees.
The missing angle = 180 - 90 - 56.7 = 33.3 degrees
I believe the answer would be 10.2
