Question

the measure of one of the angle of a parallelogram is 40 degree then finf tht meadure of its adjacent angle

Answer 1

Answer:

110 degree

Step-by-step explanation:

The sum of the adjacent sides of the parallelogram is degrees180 degrees.

As given in the question , if one angle is x, the adjacent angle will be x+40 degrees.

Sum of the adjacent angle is x + (x+40). =2x + 40.

Therefore 2x + 40 =180.

Or 2x =180 - 40 = 140.

Or x =140/2 = 70.

Therefore one angle is 70 degrees and the adjacent angle is 70+40 = 110 degrees

Answer 2

Answer:

140°

Step-by-step explanation:

let the required angle be x

sum of adjecent angles in a parallelogram is 180°(co linear angel)

so;

given angle + required angle = 180°

40+x= 180°

x= 180-40

x= 140°
