the slant height would be the hypotenuse of a right triangle. 1/2 the length of the base would be one side of a right triangle. Use the Pythagorean theorem to find the height:


89.9^2 = 9.9^2 + x ^2

8082.01 = 98.01 + x^2

X^2 = 8082.01-98.01

X^2 = 7984

X = sqrt(7984)

X = 89.35

Round to 89.4

insens350 [35]

Answer:

A. 20.5

Step-by-step explanation:

We can use the Pythagorean theorem to solve this equation for the missing side length, X.

a^2 + b^2 = c^2

We have a and b, we just need c, the hypotenuse.

14^2 + 15^2 = c^2

196 + 225 = c^2

421 = c^2

Now, we will square both sides:

The answer is about 20.5

olganol [36]
We calculate for the taxable income by subtracting the tax free allowance from the gross income.

          Taxable income = Gross income - tax free allowanc
           Taxable income = (£12,000 - <span>£6,475)
                                    = </span><span>£5,525

Hence, the taxable income is equal to </span><span>£5,525.

Net income: 
This would be equal to the gross income minus the amount of taxes to be paid.
 
                 Net income = Gross income - amount of tax to be paid
                 Net income = (</span><span>£12,000) - (0.20)($5,525)
                 Net income = $10,895

Therefore,
