Yes. Supplementary angles add to 180o, so the angle which is its own supplement would be 90o.
Suppose the supplement of the angle is x degrees. Then the angle is 180 - x degrees. Therefore the complement of the angle is 90 - (180 - x) degrees = x - 90 degrees. So 5*(x - 90) - 2*x = 40 Solve the above equation for x.
Yes, except that the answer would be an angle whose measure is negative. Such angles are quite useful in trigonometry.
Supplement means the two angles add to 180°. So that's one equation, and the other equation is that one angle is 20° than the other.Let A & B be the angles.A + B = 180A - B = 20Add the two equations: 2A = 200, so A = 100, and then substitute in to get B = 80. So the angle 100° is 20° greater than its supplement.
To draw one and a sixth times a straight angle, you first need to understand that a straight angle measures 180 degrees. To find one and a sixth times this angle, you would multiply 180 by 1.1667 (6/5). This gives you an angle measuring approximately 210 degrees. Using a protractor, you can then draw an angle of 210 degrees to represent one and a sixth times a straight angle.
