Question

5. Find the measure of all the angles of a parallelogram, if
one angles is 15° less than twice the smallest angle.​

Answer 1

So, the other angle is 15 degrees less than twice the smallest angle. since we know that in case of parallelogram, opposite angles are equal. We know that sum of all angles in quadrilateral is 360°. Hence, all the angles are 65°, 115°, 65°, 115°.
