You can use a protractor.
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.
An angle is supplementary to another if their measures add up to 180 degrees. To find the angle that is supplementary to a 75-degree angle, subtract 75 from 180. Therefore, 180 - 75 = 105 degrees. Thus, the angle that is supplementary to a 75-degree angle is 105 degrees.
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.
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.
You find the center of a screwed 45 degree elbow by bisecting the angle.
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.

.105
The angle opposite the 55 degree angle will also be 55 degrees. The other two angles will each measure 180 - 55 = 125 degrees.
An angle is supplementary to another if their measures add up to 180 degrees. To find the angle that is supplementary to a 75-degree angle, subtract 75 from 180. Therefore, 180 - 75 = 105 degrees. Thus, the angle that is supplementary to a 75-degree angle is 105 degrees.
