90 - 20 = 70 degrees.
An acute angle
360 - 20 = 340
The answer depends on knowing what the plane mirror hhas a 20-degree angle relative to!
Is 65 an acute angle
45 degree angle
It is an an acute angle that is less than 90 degrees but greater than 0.
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
90 - 20 = 70 degrees.
300° angle look like
It is an acute angle
An acute angle
staircase is made in an angle of 20 to 30 degree and it shouldn't be more then 30 degree.
360 - 20 = 340

it looks like an angle..... -.-
It is about a third of a right angle.
