Answer;
-Progressive tax
Explanation;
-According to this type of tax system, the taxes assessed are based on the taxable amount, and follow an increasing schedule. High-income earners pay more than low-income earners, and the tax rate, along with tax liability, increases as an individual or entity's wealth increases.
-Therefore; higher earners pay a higher percentage of taxes and more money in taxes than do lower-income earners
.
AO = 21
BC = 14
OC = radius of the circle = AO = 21
∴ OB = OC + CB = 21 + 14 = 35
<span>Line AB is tangent to circle O at A</span>
∴ AB is perpendicular to AO
∴ Δ OAB is a right triangle at A
Applying Pythagorean theorem
∴ OB² = AO² + AB²
∴ AB² = OB² - AO² = 35² - 21² = 1225 - 441 = 784
∴ AB = √784 = 28
