If measures opposite angles of a larallelogram are (60-x)° and (3x-4)°, then find the measures of angles of the parallelogram.
Given,
Measure of opposite angles of parallelogram = (60-x°) , (3x-4°)
= 60-x° = 3x-4° (opposite angles of parallelogram )
= 4x = 56°
= x = 
Hence angles of parallelograms = 60- 14° = 46°
Other two angles = 180-46 = 134°
