Answer:
Option b is right.
Step-by-step explanation:
Given is a picture of a parallelogram RSTU.
The angle S is given as 70 degrees.
As per properties of a parallelogram, we have
opposite angles are equal and
adjacent angles are supplementary
Since angle S =70, angle R = supplementary of 70 =110
angle T = supplementary of S =110 and
Angle U = opposite of S =70
Hence option 2 is right.
