Answer:
$55.96
Step-by-step explanation:
To find 30% of $79.95, we must multiply 79.95 by .3
We get 23.985, which can be rounded to the nearest 100th to get 23.99
So, 30% of $79.95 is $23.99
Now, we can just subtract to find the sale price.
$79.95 - $23.99 = $55.96
They are supplementary because angle 12 is congruent with angle 10 which is supplementary with angle 7 ( that means the measure of angle7+ the measure of angle 12 is 180 grades)
12 and 10 are congruent due to the fact that A and B are two parallel lines and D is a sequent (i don't know how to spell this word). i guess you get it
