1 plus 2 is equal to 3
It is 180 -64 = 116 and 64 plus 116 = a supplementary angle of 180 degrees
112.5 degrees
180 - 35 = 145. Half of 145 is 72.5 which is the smaller angle. (The other angle is 35 + 72.5 ie 107.5)
The interior angle and the exterior angle are supplementary. That's why you learned about supplementary angles ... or at least they were presented in class ... before polygons.
Supplementary angles are two angles that measure up to 180 degrees. EXAMPLE: If the an angle measures 70 degrees, to find the missing angle, you subtract 70 from 180 because supplementary angles equal 180 degrees. Your answer (in this case 110) is the answer for the measure of the missing angle.
Supplementary angles are angles that add up to 180 degrees, ie. a straight angle. Therefore, the angle supplementary to 101 degrees would be 180-101=79 degrees.
1 plus 2 is equal to 3
60 degrees and 120 degrees
It is 180 -64 = 116 and 64 plus 116 = a supplementary angle of 180 degrees
Two angles are said to be supplementary if they total 180 degrees. To find an angle's supplement, subtract its measure from 180.
false but You can find the measure of an exterior angle by using supplementary angles.
112.5 degrees
180 - 35 = 145. Half of 145 is 72.5 which is the smaller angle. (The other angle is 35 + 72.5 ie 107.5)
The methods are subtraction. -- Subtract an angle from 90° to find its complementary angle. -- Subtract an angle from 180° to find its supplementary angle.
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.)
A supplementary angle will add up to 180 degrees so to find the supplementary angle of 179 degrees, you would take 180-179 to get a 1 degree angle.
