Q13 of 95 Page 15

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°
