how do i find the degree of a right angle, split into two different angles.
ex. if m<10 = 80*, then m<11 = ?
The two angles must add to 90 degrees
so if one of them is 10
then the other one is 90 - 10
or 80
If one is 40
then the other is 90 - 40
or 50
Angles that add to a right angle are called complementary.
To find the measure of angle 11, which is splitting a right angle with an angle measure of 80 degrees, you need to subtract 80 degrees from 90 degrees.
A right angle measures 90 degrees because it is a quarter of a full circle, which is 360 degrees.
So, to calculate the measure of angle 11, you subtract 80 degrees from 90 degrees:
90 degrees - 80 degrees = 10 degrees
Therefore, the measure of angle 11 is 10 degrees.
