Answer:

\huge\boxed{\sf x = 65 \textdegree}

Step-by-step explanation:

Using trigonometric ratio cos.

Here,

  • Theta = θ = x
  • Adjacent = 12
  • Hypotenuse = 28
<h3><u>Finding x:</u></h3>

\displaystyle cos \theta =\frac{adjacent}{hypotenuse} \\\\cos \ x =\frac{12}{28} \\\\cos \ x = 0.43\\\\x = cos^{-1} 0.43\\\\x = 65 \textdegree\\\\\rule[225]{225}{2}

Gelneren [198K]

Answer:

A

Step-by-step explanation:

It looks like M is composed of all real numbers and that U = R also means its composed of all real numbers. This means that M and U are equal and both are composed of all real numbers.

To define the complement of M, it includes all values which are not in M. However, since M already has all real numbers and U doesn't have any values that M doesn't then the complement is nothing. It is an empty set with no items in it. This means A is the correct answer.
