Answer 1

B.) 50°

Explanation:

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

`tangentX=(opposite)/(adjacent)`

Insert values:

`tanX=(422)/(348)`

Use the inverse:

`X=tan^(-1)((422)/(348) )`

Insert this into a calculator:

`x=50.489`

Round to the nearest degree:

`x=50`

The angle of elevation is 50°.
