i dont no
yes complement is 90-angle and supplement 180-angle
Yes, except that the answer would be an angle whose measure is negative. Such angles are quite useful in trigonometry.
(180°-x) + (90°-x) = 240°270° - 2x = 240°30° = 2x15° = xThe measure of the angle is 15°.The supplement is 165°, the complement is 75°, and their sum is 240°.
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
