45 degree angle
First draw a 90 degree angle .Than draw a 20 degree angle from that 90 degree angle . Than the rest of the angle will be 90-20=70 .Now bisect the 70 degree angle we will get 70/2=35. Now add the rest of the angle means 35+20 =55 GOT 55 DEGREE ANGLE
staircase is made in an angle of 20 to 30 degree and it shouldn't be more then 30 degree.
A pair of supplementary angles add up to 180 degrees. Therefore, the supplement to a 20 degree angle is equal to 180 - 20 = 160 degrees.
90-20 = 70 degrees

A 20 degree angle is classified as an acute angle, which means it measures less than 90 degrees. Acute angles are commonly found in geometric shapes and are known for their sharpness. In trigonometry, a 20 degree angle can be further classified as a specific type of acute angle within the unit circle.
360 - 20 = 340
The answer depends on knowing what the plane mirror hhas a 20-degree angle relative to!
A pair of supplementary angles add up to 180 degrees. Therefore, the supplement to a 20 degree angle is equal to 180 - 20 = 160 degrees.
