Answer:
Coupon 2
Step-by-step explanation:
If you were to use coupon 1 the price will be $28.80 because %40 of $18 will be $10.80 (18 x 0.40) then add it to the other 18$ and it will sum up to $28.80. If you were to use coupon 2 the price will be $27 because if you were to take %25 of the sum of both sweaters ($36) it would be $27 (36 x 0.25).

Answer:
\angle ACB=40^{\circ}, \angle ABC=63^{\circ}
Step-by-step explanation:
Finding x:
We know that
, because it's a straight line. So,
.
We know that the sum of the angles of any triangle will be
.
So, we have that
.
Combining like terms on the left gives
.
Subtracting
from both sides gives
.
Dividing both sides by
gives
.
Finding missing angle measures:
.
.
So,
and
and we're done!
Note:
. Coincidence? If not, try and prove it!
