Answer: x=31°
Step-by-step explanation:
To find the missing angle, we need to use SOHCAHTOA. We can eliminate sine and tangent because we aren't given the opposite side. Therefore, we use cosine.
[tex]cos(x)=\frac{48}{56}[/tex] [use inverse cosine]
[tex]x=cos^{-1}(\frac{48}{56})[/tex]
[tex]x=31[/tex]
Now, we know x=31°.
