Joyce paid 54.00 for an item at the store that was 70 percent off the original price. what was the original price.

70% off means she only paid 30% so if x = original price,
54/x = 30/100.
Cross multiply
30x = 5400 so divide by 30
x = $180

Okay so for every triangle has three angles that always add up to 180 degrees. and to tell the difference between whether they are secure, right or obtuse is that acute: has one angle that is less than 90 degrees. right triangle means there is at least one angle that is exactly 90 degrees. and an obtuse angle has an angle that is bigger than 180 degrees. i’ll do #13 as an example: 13. 40 and 50 so if every triangle has 180 degrees 40+50= 90 degrees then180-90= 90 degrees so the third angle is 90 degrees and because this triangle has a 90 degree angle it means it is a right triangle
