Answer 1

Solution.

We know that the opposite angles of parallelogram are equal. So,
Angle R = Angle P = 50° and
Angle A = Angle C = 120°

Now, Angle C + Angle B = 180°
--(the sum of interior angles are 180°)
So, 120° + Angle B = 180°
To solve, we get,
Angle B = 60°

Now, In triangle POB
By the angle sum property of triangle.

x + Angle P + Angle B = 180°.
x + 50° + 60° = 180°
x + 110° = 180°
x = 180°- 110°
x = 70°.

Hence the value of x is 70°.
