One hundred thirty five 13%
The largest triangle and the triangle whose hypotenuse is x are similar. So:
(21 + 4)/x = x/4
Cross multiply:
x^2 = 100
x = 10
Your answer is incorrect. It should be 10, not 20.

The original price of the sweater was $28
Step-by-step explanation:
To find out the answer to this problem you need to first convert the percent into a decimal which would be 0.4 and then to solve the problem in one step you need it to be 140% which would be 1.4 as a decimal. Then you need to multiply 20 by 1.4 which gives you 28 and 28 would be the total cost of the shirt at it's regular price.
