Based on the radius of the circle and the origin of the beam, the angle of elevation to ensure that the beam goes through the hole is 15.95°.
The best operation to use would be the Tangent as the angle we are looking for is adjacent to the circle.
Solving gives:
tan (angle) = Radius of hole / Distance of beam
Angle = tan ā»Ā¹ (Radius of hole / Distance of beam)
= tanā»Ā¹ (10 / 35)
= 15.95°
