What's the angle's measure?Answer by oberobic(2304)   (Show Source): You can put this solution on YOUR website!a = angle s = supplement of angle a s = 180-a c = complement of angle a c = 90-a . s = 2c + 30 . s = s, so . 180-a = 2c + 30 . 180-a = 2(90-a) + 30 . 180 -a = 180 -2a + 30 . a = 30 s = 180-30 = 150 c = 90-30 = 60 . Check the relationship of s and c. s = 2c + 30 ?? 2c + 30 = 2(60)+30 = 120+30 = 150 correct . Angle = 30 degrees. . Done.
