Answer:
4 h
Step-by-step explanation:
The resting spot was at the 8 mi mark.
When Stacey reached the 16th mile, they had covered
16 mi - 8 mi = 8 mi
They took 2 h for every 1 h, so
It may be easier to do this calculation on a number line. Each jump of 2 mi represents 1 h, and there are four jumps, so they took four hours.
Answer: True
Step-by-step explanation:
When two lines intersect they form both supplementary and vertical angles.
For example if AB intersects CD at point O (as given in figure), then ∠AOD and ∠DOB are supplementary [lies on line AB] and ∠AOB = ∠COB {Vertical angles are congruent}
Since Chords are line segments that join two distinct points on the circle, it means Intersecting chords also form a pair of supplementary, vertical angles.
Hence, the given statement is true.
