Answer:
This shape is a rectangle so that means that the angles are 90°. From sum of angles of a triangle, x + 3x + 10 + 90 = 180 which means 4x + 100 = 180 → 4x = 80 → x = 20°.
Answer: 
Step-by-step explanation:
In the given picture, a parallelogram PQRS is given with angle 101°.
In a parallelogram opposite angles are equal.
Since, y is opposite to 101°.
Therefore y=101°
Also, the sum of the adjacent angles of a parallelogram is 180°
