In a right triangle, the ratio of the side opposite an acute angle to the hypotenuse is the sine of the angle. Here, that ratio is 80/445, so we have ...

sin(angle of elevation) = 80/445

Using the inverse sine function we can find the angle that has this sine value.

angle of elevation = arcsin(80/445) ≈ 10.36°

The angle of elevation is about 10°.
