Question

An angle of the parallelogram measures 85degree. Find the measure-of the remaining three angles

Answer 1

Answer:

Opposite to 85° angle is also 85° 

Adjacent two angle = 180° - 85°

= 95°

Answer 2

Let the angles of the parallelogram be A , B , C , D , We know that opposite angles of parallelogram are equal

Therefore , if angle A is 85 degree then angle C is also 85 degree

And also sum of adjacent angles of the parallelogram is 180 degree

Therefore , Angle A + Angle B = 180

85 + angle B = 180

Angle B = 180 - 85

Angle B = 95 degree

As angles opposite to each other are equal in parallelogram

Therefore , Angle B =Angle D = 95 degree
