Answer:If a line segment intersects two straight lines forming two interior angles on the same side that sum to less than two right angles, then the two lines, if extended indefinitely, meet on that side on which the angles sum to less than two right angles
-9.1 < d - 6.3
add 6.3 to both sides
-2.8 < d or d > -2.8
Answer:
Step-by-step explanation:
So this is a quadratic sequence.
3, 12, 22, 33, 45, 58, 72
9 10 11 12 13 14
9, 10, 11, 12, 13, 14
1 1 1 1 1
This means the next one must be 15 so
3, 12, 22, 33, 45, 58, 72, x
9 10 11 12 13 14 15
x= 72+15
x= 87
