Its true because of the rule (cpct)corresponding parts of congruence triangle.
Answer:
460 miles, 1 week
Step-by-step explanation:
249 per week + 0.25 per mile
180 per week + 0.4 per mile
after 460 miles in 1 week the cost will be the same
We know that
The inscribed angle Theorem states that t<span>he inscribed angle measures half of the arc it comprises.
</span>so
m∠D=(1/2)*[arc EFG]
and
m∠F=(1/2)*[arc GDE]
arc EFG+arc GDE=360°-------> full circle
applying multiplication property of equality
(1/2)*arc EFG+(1/2)*arc GDE=180°
applying substitution property of equality
m∠D=(1/2)*[arc EFG]
m∠F=(1/2)*[arc GDE]
(1/2)*arc EFG+(1/2)*arc GDE=180°----> m∠D+m∠F=180°
the answer in the attached figure
Check the picture below, let's use those two points on the line to get its slope.
