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.
find the sum of the measures of the interior angles of 13-gon.
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.)
Supplementary angles add up to 180 degrees. So, if x is the supplementary angle to 148.7 degrees, solve for x: 148.7+x=180 x=180-148.7=31.3 degrees
60 degrees and 120 degrees
112.5 degrees
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 any angles in which their degrees add to a sum of 180o. In the related links you will find an example of Supplementary angles.
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.
Supplementary angles add up to 180 degrees on a straight line
Supplementary angles total 180 degrees. If you have one angle, subtract it from 180 to find its supplement.
Each of the remaining two angles is 32.5degrees.(32.5) + (32.5) + (115) = 180
you can use up to 2 angles in a supplementary angle. Just find 2 angles to fit into 180 degrees.
in any parallelogram, vertical angles are congruent, while any two adjacent angles are supplementary. The area of a parallelogram is bh (base multiplied by height), while the perimeter is 2(b+h), or 2b+2h.
Supplementary angles add up to 180 degrees on a straight line
I can't find a name for it but an example would be a trapezoid. Some might have congruent angles but not all do.
