Since CB || ED and CB = ED,
by the alternate interior angles theorem,
mE = mC, and mD = mB.
with CB = ED, we can conclude that CBF = EDF, by SAS congruent theorem.
Answer= 6.5y+12
distribute the 5 in the parentheses:
(-6y-3) + (15+12.5y)
(you can take away the parentheses after this step)
then add like terms together.
12.5y + (-6y) = 6.5y
15 + (-3) = 12
make it one expression.
6.5y + 12
You’re going to be adding by .05
so the first one would be 5.86 and the second one would be 6.01
hopefully this helps!
False. An acute angle's measure is anywhere from 0 to 90 degrees. So it doesn't have to be 30 degrees, it can be anywhere in that range.
