Make a line parallel to RT to create alternate internal angles
Answer:
40, 41, 42
Step-by-step explanation:
x +x+1+x+2=123
3x+3=123
3x=123-3
3x=120
x=120:3
x=40(the first number
40+1=41 (the second number
40+2=42 (the third number

Therefore, whereby a line which is defined by two end points, is seen to be the sum of points between the two end points.
