What is cos (x)? 48/58 58/48 26/58 58/26

Evgen [1.6K]

We have to calculate the length of the missing side.
Use the Pythagorean theorem:

$a^2+32^2=58^2\\\\a^2+1024=3364\ \ \ |-1024\\\\a^2=2340\to a=\sqrt{2340}\\\\a=\sqrt{36\cdot65}\\\\a=6\sqrt{65}$

$\cos x=\dfrac{6\sqrt{65}}{58}=\dfrac{3\sqrt{65}}{29}$

I think. Your answers to choice are wrong.

Form a polynomial whose zeros and degree are given. Zeros:-4,4,5; degree:3

777dan777 [17]

Answer:

f(x) = x³ − 5x² − 16x + 80

Step-by-step explanation:

The degree is 3, so there are exactly 3 zeros.

The zeros are -4, 4, and 5.

f(x) = (x + 4) (x − 4) (x − 5)

f(x) = (x² − 16) (x − 5)

f(x) = x³ − 5x² − 16x + 80
