The second condition tells you that

is half the size of

, so

, which could be rewritten in several ways. In standard form, that would be

.
The answer would be B C E hope this helps :)
Answer:
15
Step-by-step explanation:
30 subtract 15 = 15 and both the 10 and the other 10 are the same
The limit does not exist at the jump discontinuity at <em>x</em> = -2.
From the left, the green-ish curve approaches 4; from the right, the orange curve approaches 6. These one-sided limits are not equal, so the two-sided limit does not exist.
Calm Down this is a nasty proof
CB is parallel to ED (Given)
CB is congruent to ED (Given)
Angle CBF is congruent to Angle EDF (Vertical Angles)
Angle DEF is congruent to Angle BCF (Alternate Interior Angles)
Angle EDF is congruent to Angle CBF (Alternate Interior Angles)
Therefore we now have enough information to solve. We have a side angle side triangle here so.....
Triangle CBF is congruent to Triangle EDF because of the Side Angle Side Theorem.
Good Luck and Your Welcome
