If the central angle is 70 and the radius is 8cm, how do you find out the chord lenght?
If the radius is 8cm and the central angle is 70, how do yu workout the chord lenght?
right angle!
You find the center of a screwed 45 degree elbow by bisecting the angle.
You can use a protractor.

the cotangent of a 50 degree angle is -3.678 This is in Radians. The cotangent of a 50 degree angle is .8391 (rounded) degrees.

the missing angle is 93 degrees. you find that out by adding 53 and 34 and then subtracting them from 180. :)
I need to know how to find each angle measured to the first degree. Such as: Sin B= 0.4848
Find a square and draw lines on the diagonals. The angle between a diagonal line and side line is 45 degree.
The 90 degree angle in a right angle triangle is opposite its hypotenuse.
It is easy to draw an equilateral triangle without a protractor. That gives a 60 degree angle. It is then simply a matter of bisecting the 60 degree angle, using an unmarked rule and compass, to get a 30 degree angle.
