90 degrees
Unless you are ready for some complicated trigonometry, I would suggest that you use a protractor and draw a 50 degree angle BEYOND a right angle.
We assume A is the angle between the boards where they meet.A = (180 - 50 - 50) = 80 degrees.
It is 40 degrees
looks like a crotch
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.
Any polygon can have a 50-degree angle. It doesn't have to, but it can.
A 40 degree angle is the COMPLEMENT of a 50 degree angle.
90 degrees
Any angle under 90 degrees is an acute angle. Any angle greater than 90 degrees and less than 180 is an obtuse angle. So a 50 degree angle would be an acute angle.
It is an isosceles triangle because the third angle must measure 50 degrees
Acute angle
cos(50) = 0.6428 (rounded)
cotangent(50) = 1/tangent(50) = 0.8391
50° angle measure 50° m?= 50° replace the question mark with the line's name, or what the line is called.
