Step-by-step explanation:

Since you are given adjacent and hypotenuse use sin 53 = add/hyp

Answer:

f(x) = $ x^4 - 2x^3 + 49x^2 - 18x + 360 $ is the required polynomial.

Step-by-step explanation:

Given the zeroes (roots) of the polynomial are $ -3i $ and $ 2 + 6i $.

We know that complex roots occur in conjugate pairs.

So, this means that $ +3i $ and $ 2 - 6i $ would also be the roots of the polynomial.

If $ \pm 3i $ are to be the roots of the polynomial then the polynomial should have been: $ x^2 + 9 = 0$.

Now, to determine the polynomial for which $ 2 \pm 6i $ would be the roots.

Roots of the polynomial are nothing but the values of x (any variable) that would make the polynomial zero.

⇒ $ x = 2 + 6i \hspace{35mm} x = 2 - 6i $

⇒ $ x - 2 - 6i = 0 \hspace{25mm} x - 2 + 6i = 0 $

The required polynomial would be the product of all the above polynomials.

$ i.e., (x^2 + 9)(x - 2 + 6i)(x - 2 - 6i) = 0 $

Multiply this to get the required equation.

⇒$ (x^2 + 9)(x^2 - 2x + 40) $

$ \implies x^4 - 2x^3 + 40x^2 + 9x^2 - 18x + 360 = 0 $

∴ The required polynomial is x⁴ - 2x³ + 49x² - 18x + 360 = 0.
