Value of x. hypotenuse is the square route of 20 and one leg is x-2 other leg is x

Step-by-step explanation:

The Pythagorean Theorem is:

Where the hypotenuse is "a" and "b" and "c" are the legs of the triangle.

Knowing that:

Susbstitute values into the Pythagorean Theorem and solve for x:

Remember that the square a binomial is:

Then:

Use the Quadratic formula:

Choose the positive value.

Then:

$3720

step-by-step explanation:

taxable income = $31000

as per the 2018-2019 us tax bracket, the tax rate is 12% for an individual whose taxable income is between $9,526 to $38,700.

so, the tax to be paid by him = 12% of 31000
