X = 180 - Y so 180 - Y = 2x + 4 and Y = 4x + 20 so 180 - 4x - 20 = 2x + 4 therefore 6x = 156 so x = 26 making Angle X = 56o and Angle Y = 124o
If cos y = 0.5135 then y = 59.1°.
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-
A = 60 B = 20 C = 140 This can have a large number of answers.
x and y are complementary so x + y = 90 and so y = 90 - x z and q are complementary so z + q = 90 and so q = 90 - z x = z so 90 - x = 90 - z that is y = q
