That will depend on the size of the original angle of and what kind of shape it is which has not been given.
You can solve by substituting (x) for the unknown angle and (x + 40) for the angle plus 40 degrees and set the equation as: x + (x + 40) = 90 (then simplify) 2x + 40 = 90 (then isolate the known from unknown by subtracting 40 from each side of the equation) 2x = 50 (divide both sides by 2 to solve for x) x (the unknown angle) = 25 degrees now you can substitute the value of the angles to prove the equation.
A 40 degree angle is the COMPLEMENT of a 50 degree angle.
Any degree less than 90 degrees. An acute angle can be 40, 50, 20, 75, or 66 degrees.any angle that is less than 90 degrees...
40 degrees
An angle that is 40 degrees is an acute angle. Anything below 90 degrees is acute while anything above is obtuse.

Supplementary angles, when added together, equal 180 degrees. If we let the smaller angle equal X we know that X + (2X + 60) = 180 3X+60=180 3X=120 X=40 The small angle is 40 degrees. The larger angle is 2(40)+60=140 degrees.
A 40 degree angle is the COMPLEMENT of a 50 degree angle.
