Question

if one of four angles of a parallelogram is 75degree , then write the measures of other angle​

Answer 1

1. Since parallelogram's opposite angle are equal
2. So now, let we consider A=75°, B=x,C=75°,D=x
3. now we know that sum of angles of parallelogram is 360°
4. we will get A+B+C+D=360°putting values
5. 75+75+x+x=360
6. 150+2x=360
7. 2x=210x=105
8. so we've got four angles i.e.75°,75°,105°,105°
9. Hope it'll help u
