90 - 20 = 70 degrees.
What Is a closed plane figure with 8 straight sides called?

What is the reflex angle of twenty degree?
Reflex angle is "A Reflex Angle is more than 180° but less than 360°" by definition; however, if the "20°" you are talking about is the "acute" angle, then the reflex angle is: 360° - 20° = 340°

Light strikes a mirror at 20 degrees to the normal what will the angle of reflection be?
The reflection angle will also be 20 degrees from the normal on the other side of the normal in the same plane.
What is the angle of reflection 20 degrees from the surface?
The key is to recognize that "the angle of INCIDENCE is equal to the angle of REFLECTION", for an 'Elastic' collision. So the answer is 20 degrees.
How many images are formed when two plane mirrors tilted an angle 72 degrees?

How does angle of incidence control the intensity of solar radiation received at the earth's surface?
The angle of incidence is what trajectory the suns burst is taking. If the burst is pointed 20 degrees in any direction, slightly away from the earth, then the intensity of the impact on earth would be less severe since only a portion of the burst is actually making contact. While the rest of it flies into space for millions and millions and millions of kilometers.
A bus driver looks into a plane mirror 20 cm long which is placed 50 cm in front of him if the rear window is 500cm away from the plane mirror through what length of the rear window can he see whene?
The answer is 50 times the mirror added by 500 and sbtract by X and divide by 2 and also you ned to destroy the whole universe and eat your food b
When the angle of refraction is 20 degrees what is the angle of incidence?
It depends what substance the refraction is taking place in. You need to know the refractive index, n then you can use the formula (sin(i))/(sin(r)) = n so sin(i) = n * sin(20) and i = arcsin ( n*sin(20) ) or, equivalently: i = sin^-1 ( n*sin(20) ) If you were using a glass block block, then n=1.5 and i = arcsin (1.5*sin(20)) = 30.86588247 = 30.9 degrees (3 s.f.)
