right angle!
You find the center of a screwed 45 degree elbow by bisecting the angle.
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.

right angle!
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.

The angle opposite the 55 degree angle will also be 55 degrees. The other two angles will each measure 180 - 55 = 125 degrees.
It has a 90 degree angle..
