Supplementary angles add up to 180°
Complementary angles add up to 90°
Let the angle be θ; then form an equation from the known facts:
1) Supplement: 180° - θ
2) Complement: 90° - θ
→ twice complement is (90° - θ) × 2
→ increased by 65° is (90° - θ) × 2 + 65°
These two are equal, thus:
180° - θ = (90° - θ) × 2 + 65°
→ 180° - θ = 180° - 2θ + 65°
→ θ = 65°
The angle is 65°.
Subtract the angle from 90 degrees and you have the complement Subtract the angle from 180 degrees and you have the supplement
140 degrees
It is 90 degrees more than the original angle.
plus the angle degrees with the angle complement so equals into 135 degrees
They are: 85 degrees and 175 degrees respectively
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.
Supplement angle: 180-65.8 = 114.2 degrees Complement angle: 90-65.8 = 24.2 degrees
Subtract the angle from 90 degrees and you have the complement Subtract the angle from 180 degrees and you have the supplement
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.
128 degrees
complement is 90 degrees minus angle supplement is 180 degrees minus angle 90-77 = 13 = complement 180-77 = 103 = supplement
140 degrees
It is 90 degrees more than the original angle.
plus the angle degrees with the angle complement so equals into 135 degrees
19 degrees and 109 degrees respectively
They are: 85 degrees and 175 degrees respectively
