20 percent of 100 is 20 so the dress is 80 on sale so you need 20 which is 25% of 80
20 plus 80 equal 100 the starting price
25%
Answer:
Complementary, x=60.
Step-by-step explanation:
The angles are complementary because they add up to 90 degrees, opposing supplementary angles, which add up to 180 degrees. To find x, we need to form an equation to represent the problem. We know the two angles add up to 90 degrees, so we can use that to make the equation.
(x-30)+x=90 Simplify.
x-30+x=90
2x-30=90 Add 30 to both sides.
<u>+30 +30</u>
2x=120 Divide both sides by 2.
x=60
We can also find the value of the angles by plugging in x.
Angle 1: (x-30)
(60-30)
30 degrees
Angle 2: x
60 degrees
(You can also notice that the two angles add up to 90 degrees, which is another way of telling that the angles are complementary.)

I hope it helps! I will show you screenshots in the comments
Base is 1.11 and it is more than 1. So it is growth
1.11=1+0.11 = 1+(11/100)
11% growth
