Answer:
5
Step-by-step explanation:
slope = rise/run = (7-y)/(-5-(-2)) = -2/3
3(7 -y) = -2(-3) . . . . . multiply by 3(-3)
7 -y = 2 . . . . . . . . . . . divide by 3
7 -2 = y = 5 . . . . . . . . add y-2
The value of y is 5.
Angle 1 + angle 6 is equal to 180° because they are on the same line.
so if angle 6 is 125° so angle 1 is:
180 - 125 = 55° :)))
i hope this is helpful
have a nice day
