let x = measure of the mystery angle and y = measure of its supplement By definition of supplement, x+y = 180 since any angle and its supplement sum to a straight angle The problem gives us that 3x = y Substituting in 3x for y in the supplement equation gives us x + 3x = 180 4x = 180 x = 180/4 x = 45 Check our answer: The supplement of 45 degrees is 180 - 45 = 135. 45*3 = 135. Therefore, the answer is 45 degrees.
An angle whose measure is 20 degrees!
The measure of an angle whose sides overlap is 0 degrees. It is than not an angle, but rather a line.
An angle of 165 degrees is an obtuse angle because it is greater than 90 but less than 180 degrees.
Suppose the angle is x degrees. Then its supplement is 180-x degrees. But you also know that the supplement is 8x so 8x = 180 - x deg Add x to both sides: 9x = 180 deg Divide both sides by 9: x = 20 deg
179 degrees
The supplement of 17 degrees is 163 degrees.
60o is the supplement to an angle of 120o
148
The angles are 157.5 degrees and 22.5 degrees
It is 180 -64 = 116 and 64 plus 116 = a supplementary angle of 180 degrees
Supplement angles add up to one hundred eighty degrees, so the supplement of an eighty five degree angle would be a ninety five degree angle.
54 degrees 180 - 126 = 54
Supplementary angles are two angles whose sum equals 180 degrees. Therefore, the supplement of a 56 degree angle would be 124 degrees. (180-56=124)
The measure of an angle whose complement is four ninths its supplement?æ is 18 degrees. It is calculated as follows: let y be the angle, its complement will be (90-y) degrees and its supplement will be (180-y)?æ degrees and?æ since it complement is?æ 4/9 its supplement; then?æ it is?æ?æ(90-y)= 4/9(180-y).?æ Hence, you will get 18 degrees when you solve the equation.
An angle whose measure is exactly 180 degrees is a straight angle.
Acute Angle: An angle whose measure is less than 90 degrees and greater then zero degrees is called an acute angle. Right Angle: An angle whose measure is 90 degrees is called right angle. Obtuse Angle: An angle whose measure is greater than 90 degrees and less than 180 degrees is called obtuse angle. Straight Angle: An angle whose measure is 180 degrees called a straight angle. Reflex Angle: An angle whose measure is greater than 180 degrees and less than 360 degrees is called a reflex angle. Complete Angle: An angle whose measure is 360 degrees is called a complete angle. Zero Angle: If the measure of an angle is zero it is called a zero angle.
