A must be parallel to b.
Proof:
∠3 = <span>∠13 (given)
</span>∠15 = <span>∠13 (vertically opposite angles are equal)
Since </span>∠13 = ∠3 and ∠13 = ∠15, ∠15 = <span>∠3
Then, a must be parallel to b (transverse line d cuts parallel lines producing converse alternate angles that are equal (ie </span>∠15 = <span>∠3))
</span>
(2x+1) + (2x+3) + (2x+5) + (2x+7) + (2x+9) = 145
10x + 25 = 145
10x = 120
x = 12
2x + 1 = 25
Sequence = 25 +27 +29 +31 +33
Third number = 29

Answer:
x = 22
Step-by-step explanation:
The midsegment BF is half length of the base segment CE, so you have ...
2x = 88/2
x = 22 . . . . . divide by 2
Answer:
1.26 minutes
Step-by-step explanation:
Step one:
given
Eric ran a mile in 10.84 minutes,
Kay ran a mile in12.79 minutes, and
Rosie ran a mile in 9.58 minutes
Required
The time difference between Eric run and Rosie
Step two:
The difference is
10.84- 9.58=1.26 minutes
