180 - 35 = 145. Half of 145 is 72.5 which is the smaller angle. (The other angle is 35 + 72.5 ie 107.5)

If 4 to 5 is the ratio then the smaller angle is 80 degrees

Supplementary angles add up to 180 degrees

The sum of complementary angles is 90°. The sum of supplementary angles is 180°. EXAMPLE : 27° is the complementary angle to 63° and the supplementary angle to 153°.

Definition of a supplementary angle: an angle that is supplementary to another angle is an angle in which the sum of both angles forms a straight line or 180 degrees.Definition of a right angle: an angle whose measure is 90 degrees.Using these terms, let's put them into an equation.Right angle + Supplementary angle = 180.90 + Supplementary angle = 180.Subtract 90 from both sides.Supplementary angle = 180 - 90Supplementary angle = 90 degrees.Alternatively, you can think that two right angles are equivalent to a straight line and that all right angles are congruent and therefore; their supplementary angles are also congruent.

Supplementary angles are angles whose sum is 180° . The supplementary angle to 110° is therefore 70°.

Supplementary angles forms a 180o angle (or a straight line). Complementary angles form a 90o angle.

well right angle is 90 degress or a perfect l a straight angle is 180 degress

supplementary angles

A supplementary angles are 2 angles that equal 180. 70+110=180

Supplementary Angles

yes because a supplementary angle is two angles where the sum of the angles is 180 degrees.

The angle sum of a pair of supplementary angles is 180 degrees.
