Answer:

B.) 50°

Step-by-step explanation:

This is basically asking for the angle to the left of the right angle. Use the tangent ratio:

[tex]tangentX=\frac{opposite}{adjacent}[/tex]

Insert values:

[tex]tanX=\frac{422}{348}[/tex]

Use the inverse:

[tex]X=tan^{-1}(\frac{422}{348} )[/tex]

Insert this into a calculator:

[tex]x=50.489[/tex]

Round to the nearest degree:

[tex]x=50[/tex]

The angle of elevation is 50°.
