You should use a special device for measuring angles - a protractor. With a ruler, it is much more complicated, but still possible: you can mark two points on the angle, one on each side; measure the distance from the vertext of the angle to those points; measure the distance between the points; then use the Law of Cosines to calculate the angle.

In triangle ABC the measure of angle B is 40 less than the measure of angle A the measure of angle C is 20 more than twice the measure of angle A what is the measure of angle C?
A = 60 B = 20 C = 140 This can have a large number of answers.

Using a ruler how to measure an angle?
You cannot measure an angle using a ruler.
How do I measure a right angle?
A ruler
What is the definition of angle ruler?
well an angle ruler is used to measure the interior angles of a shape or an agle period
How to find a measure in each angle?
by using a ruler
Can you measure angles with a ruler?
No, a ruler is used only to measure length, width or height. You must use a protractor in order to measure the degrees in an angle.
How do you find the side of a triangle?
To find the degree of angle of a side of a triangle, a protractor is needed to measure the angle. Place the '0' on the protractor on the point of the angle and look at the top part to determine degree of angle. To measure the length of a triangle side, a simple ruler can be used to measure the length.
What can you use to measure angles other than a protractor?
A ruler. Add a line to make the angle into a triangle, measure the sides and use trigonometry.
What is an angle ruler?
An angle ruler is a tool used to measuring angles like a protractor. An angle ruler is more accurate than a protractor.
How do you measure the incident ray?
use a ruler to measure the length. use a protractor to measure the angle of incidence. i dont think there is any other way to measure a ray. unless you are talking about the angle which you most likely arent since the question clearly states 'ray'.
Explain what the measure of an angle is?
the measure of an angle is the degrees of an angle.
