Question

The sum of two opposite angles of a parallelogram is 300⁰ . Find the measure of other two
Angles ?
9. Find the length of each side of a rhombus whose perimeter is 60 cm.​

Answer 1

In a parallelogram opposite angles are equal
Let one angle be x
Other opposite angle is also x
Sum of the two angles =300
X+X =300
2x=300
X=300/2
X=150
In the parallelogram the two opposite angles are 150.The other two angles are also opposite and equal
Let the two opposite equal angles be y
Sum of angles of parallelogram =360
X+X+Y+Y =360
300+2Y=360
2Y=60
Y=60/2
Y=30
Therefore the angles of parallelogram are 150,150,30,30
