Question

Two adjacent angles of a parallelogram are 3 x - 4 degree and 3 X + 10 degree find the angles of the parallelogram

Answer 1

Adjacent angle sum = 180°
3x - 4 + 3x + 10 =180
6x + 6 = 180
X + 1 = 30
X = 29°

Angle 1 = 3x - 4
. . . . . . . = 83°

Angle 2 = 3x + 10 = 97°

Answer 2

(3x - 4) + ( 3x + 16) = 180
6x + 12 = 180
6x = 180 - 12
6x = 168
x = 168/6
x = 28 degrees. (3x+16)=100 degrees. (3x-4)=80degrees
