Answer:
#10=6 #11=90 #12=-10
Step-by-step explanation:
15-9=6
59+31=90
5+2-y=-3
7-y=-3
7-10=-3
The formula of a slope:

We have the points (4, -4) and (k, -1) and the slope m = 34.
Substitute:

1st dot (0,48) then each dot after than subtract 6 from the Y and add 1 to the x
2nd dot (1,42)
3rd dot (2,36)
etc.
Answer:
140°
Step-by-step explanation:
∠ABC is an inscribed angle and its measure is half the measure of the intercepted arc, which is arc AC
Therefore the measure of arc AC is 2(70) = 140°
∠AOC is a central angle and its measure is equal to its intercepted arc, which is arc AC.
So, m∠AOC = 140°
