We know that adjacent angles of a parallelogram are equal.
So, (3x – 4)° + (3x + 10)° = 180°
3x° + 3x° – 4 + 10 = 180°
6x = 180° – 6°
x = 174°/6
= 29°
Measure of adjacent angles are,
(3x – 4)° = 3×29 – 4 = 83°
(3x + 10)° = 3×29 + 10 = 97°
We know that Sum of adjacent angles = 180°
∴ Measure of each angle is 83°, 97°, 83°, 97°.
