It should be 121, or +4 or -4 from that. But I am pretty sure it is 121
Answer:
-1/2
Step-by-step explanation:
pass (0,1) (2,0)
slope = rise/run = -1/2
If you are given the measure of angle 4, then we know angle 2 is equal since it is a vertical angle. The angle of a line is 180 degrees, so subtract the measure of angle 4 (and/or 2) which will give you the angle measure for both angle 1 and 3, since those are also equal due to vertical angles. Hope that helped! :)
