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.
Very simple, let's mount a linear system: x=measure of the angle; y=supplement; z=complement: I:x+y= 180; II:x+z= 90; III: y+z= 150; Summing I with II we have: I+II: 2x+y+z= 270; III: y+z=150 Now, subtracting III from I+II we have a simple equation: 2x=120; >x= 60< So, the angle whose sum of the measures of its complements and supplement is 150, has 60 degrees.
Let's call our angle in question X, and it's compliment Y. Being a compliment means that X + Y = 90 degrees, so if X is 45, then Y must also be 45, making the answer to your question yes.
Supplement of an angle measure x* be y*=(180-x*). Or x+y=180* for the problem x=9y => x+y = 9y+y=10y=180 => y=18* and x =172*
x+y=180 y= x+38 x+(x+38)= 180 2x+38=180 -38 =-38 2x = 142 x= 71 plug it in equation 71+71+38= 180 angle 1 = 71 angle 2 = 109

The complement of an angle is the degree which makes the angle add up to 90 degrees. Therefore: complement of y= 90-53 = 37.
Complementary angles add up to 90 degrees so if y = 8x-20 degrees then the complement of y is 90 - (8x - 20) = 110 - 8x degrees.

90 -y = complement 180 - y = supplement
105 degrees
Supplementary angles add up to 180 degrees
Yummy
A triangle will always have a total of 180 degrees when adding all inside angles.corner x = 50corner y =75corner z = unknownx+y+z=180180-x-y=z180-50-75=zz=55 degrees
It makes you look young.Young is the compliment.
x + y = 90 x − 2y = −17
we know that a supplementary angles when sum up is equal to 180 degrees. we let y-be the supplementary angle of v therefore, v+y=180 then, y=180-v that will be now the supplementary of the angle v. -by:-kidz-
