35, 145
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.
180 - 35 = 145. Half of 145 is 72.5 which is the smaller angle. (The other angle is 35 + 72.5 ie 107.5)
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.
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°.
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
Supplementary angles are angles whose sums =180 degrees. You have a 65 degree angle + it's supplementary angle = 180 degrees. So, to find the supplementary angle, subtract 65 from 180. 180 - 65 = supplementary angle. 115 = supplementary angle. To check, add the angles together. 65 + 115 = 180 (check) (Also, you might be working with complimentary angles. Complimentary angles are angles whose sum = 90 degrees.)
yes because a supplementary angle is two angles where the sum of the angles is 180 degrees.
