For 2 sweaters for that price what percent discount is that?
Harrizon [31]

Answer: 75% off


Step-by-step explanation:

Your first sweater is the full 100% of the cost. The second it only 50 percent. If you add these to find out how many percent you will pay which is 150 for both. If you were to divide by 2 you get 75 percent off each sweater. The first sweater is $48 the second you multiply by .5 (as its 50 percent off ) and the cost is $24 dollars. 48 plus 24 is 72 then that divided by 2 is 36. Now 36$ is the price per sweater.  36/48 or  3/4 (which is 75%)

If m angle A is 155 degrees what is m angle c?
Lubov Fominskaja [6]
Hi again! If the measure of angle A is 155 degrees, then the measure of angle C is also 155 degrees because vertical angles are congruent. Vertical angles are the two angles created when two lines intersect that are NOT linear.
