180-x= 2(90+x) - 60
180-x=180+2x - 60
-x=-60
x=60
Are you in my honors geometry class?
The algebra is wrong. the third line should read
-3x=-60
x=20
therefore the complement is 70o
This agrees with the answer in the back of the book.
19 degrees and 109 degrees respectively
Supplement angle: 180-65.8 = 114.2 degrees Complement angle: 90-65.8 = 24.2 degrees
The angle= 36, the supplement= 144, the compliment=54

The complement of an acute angle A is the angle 90° - A. The complement of 13° is 77°.
Complement . . . another angle, of 53 degrees Supplement . . . another angle, of 143 degrees
An angle of 108 degrees does not have a complement because is greater than 90 degrees. Its supplement angle has a measure of 180 - 108 = 72 degrees.
The question asks for the complement of (the supplement of (80 degrees) ). We have to find the supplement of 80 first, and then find the complement of the supplement. The supplement of an angle is (180 - the angle). The complement of an angle is (90 - the angle). The supplement of 80 degrees is (180 - 80) = 100 degrees. The complement of that supplement is (90 - 100) = -10 degrees.
19 degrees and 109 degrees respectively
Supplement angle: 180-65.8 = 114.2 degrees Complement angle: 90-65.8 = 24.2 degrees
The supplement of an angle is the angle that, when added to the original angle, equals 180 degrees. The complement of an angle is the angle that, when added to the original angle, equals 90 degrees. Therefore, the supplement of the complement of a 38-degree angle would be the angle that, when added to the complement of 38 degrees (52 degrees), equals 180 degrees. This angle would be 128 degrees.
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.
Subtract the angle from 90 degrees and you have the complement Subtract the angle from 180 degrees and you have the supplement

The angle= 36, the supplement= 144, the compliment=54
The supplement of A is 180 - A The complement of A is 90 - A So, 180 - A = 2*(90 - A) + 20 or 180 - A = 180 - 2A + 20 So A = 20 degrees
An angle and its complement have to add to 90 degrees. 77 and 13 add to 90. 13 is the complement of 77. You will also be doing supplement. They add to 180.
