The last one: the arc AB is a semicircle.
a semicircle is 180 degrees
1 and 24
2 and 12
3 and 8
4 and 6
To calculate the slope you need to do (y2-y1)/(x2-x1). So you would get:
(17-12)/(4-9)
5/-5
=-1
Hope this helps.
Answer:
Step-by-step explanation:
1) corresponding angles
2)alternate interior angles
3)alternate interior angles
4)corresponding angles
2x-7=123
2x=130
x=65
5)corresponding angles
6x-11=5x
6) alternate interiot
40=14-2x
26=-2x
-13=x
Answer:
2x +3x =7-13=4+8
