Step-by-step explanation:

AC² = AD² + BC² = x² + x² = 2 x²

AF² = AC² + CF² = 2 x² + x² = 3 x²

3 x² = 20² = 400

Sales tax rate for the above sweater is charged at the rate of 8%

Step-by-step explanation:

Sweater’s cost initially- 28$

Cost of Sweater after 30.24$

Sales tax rate deducted?

Analysing the above-provided details we conclude that an increase in the cost was probably due to the addition of sale tax.

Sales tax charged= Cost of the sweater after charging- initial cost

= 30.24$-28$

=2.24$

Percentage of sales tax charged= (sales tax charged/initial cost) *100

Substituting the values of the sales tax and initial cost in the above-provided equation-

= (2.24/28) *100

=8%

Hence the Sales tax charged at the sweater was 8%
