Question

If the smaller angle of parallelogram is 30 dgree ,then what is the measure of the bigget angle.

Answer 1

In parallelogram opposite angles are same , and the interior angle on the same side of the transversal are supplimentary,i.e.
30° + x =180
⇒x= 150°
thus angles are 150°, 30°,150°, 30°
hence biggest angle is 150°
