In parallelogram PQRS,one of its interior angles measure 80°. Find out the measure of the remaining angles.

Answer»

In a parallelogram OPPOSITE ANGLES are EQUAL and opposite sides are PARALLEL. thus two angles on the same side are supplementary

therefore, in the parallelogram

the angle opposite to the 80* will be 80*

and the other two angles will be

2x + 2(80) = 360

2x = 360* - 160*

x = 200/2 = 100

Step-by-step explanation:

As we know that x2 + 1/x2 = 18 When ADDING 2 on both sides, we get x2 + 1/x2 + 2 = 18 + 2 x2 + 1/x2 + 2 × x × 1/x = 20 (x + 1/x)2 = 20 x + 1/x = √20 When subtracting 2 from both sides, we get x2 + 1/x2 – 2 × x × 1/x = 18 – 2 (x – 1/x)2 = 16 x – 1/x = √16 x – 1/x = 4Read more on Sarthaks.com - HTTPS://www.sarthaks.com/633722/if-x-2-1-x-2-18-find-the-values-of-x-1-x-and-x-1-x

In parallelogram PQRS,one of its interior angles measure 80°. Find out the measure of the remaining angles.​

In a parallelogram OPPOSITE ANGLES are EQUAL and opposite sides are PARALLEL. thus two angles on the same side are supplementary

therefore, in the parallelogram

the angle opposite to the 80* will be 80*

and the other two angles will be

2x + 2(80*) = 360*

2x = 360* - 160*

x = 200*/2 = 100*

The angles of parallelogram are 100,80,100,80
