It is a right triangle.

Step-by-step explanation:

We know that 5, 4 and 3 is a Pythagorean Triple. In this instance, however, the Hypoteneus is 50, with the other sides being 40 and 30. This is simply the Pythagorean triple but ×10 larger.

You can also check this by:

To solve for the pretax rate of return, we can use this formula:

<span> After-tax return = Pre-tax return x (1 – Marginal Tax Rate). </span>

10.40% = Pre-tax return x (1 – Marginal Tax Rate);

<span>Pre-tax return = 10.40% / (1 – Marginal Tax Rate) = 17.33%</span>
