Answer:

x = 1 degree

Step-by-step explanation:

Using the Pythagorean theorem, a^{2} + b^{2} + c^{2} we can find the unknown side then use SOHCAHTOA to find the unknown angle

First step:

a^{2} + b^{2} = c^{2} \\45^{2} + 92^{2} = c^{2} \\2025 + 8464 = c^{2} \\10489 = c^{2} \\

Take the square root of both sides

\sqrt{10489} = \sqrt{c^{2} } \\102.4 = c

Now to find the angle use SOHCAHTOA

Cosine = \frac{Adjacent}{Hypotenuse} (The side we found is adjacent)(Hypotenuse is the longest side)

            = \frac{102.4}{92}

             = 0.999

Approximately 1 degree.
