Question

If one angle of a parallelogram is 60º. Find the measure of all other angles of parallelogram.​

Answer 1

Step-by-step explanation:

sum of parallelogram= 360°

their are 4 sides in parallelogram

let the remaining sides be x

x+x+x+ 60°= 360°

3x+ 60° = 360°

3x= 360°-60°

3x= 300°

x= 300°/3

x= 100°

each side be 100°

please rate my answer and also follow me

Answer 2

Step-by-step explanation:

one angle of parallelogram is 60°

then its adjacent angle is 120°(180°-60°=120°)

opposite angles of a parallelogram is equal

so opposite angle of 60°=60°

opposite angle of 120°=120°

the other angles are 60°,120°,120°
