Given-Angle QPO = angle PRQ( alternate interior angles)
Also, QOR =90( the diagonal bisect each other at 90 degree)
In triangle QRO,
The sum of all angles of a triangle= 180
SQR+PRQ+QOR=180
SQR+ 30+90=180
SQR+120= 180
SQR=180-120
SQR =60
I hope this helps you
Step-by-step explanation:
We know that opposite angles in a parallelogram are equal. Therefore, angle QPS is also 30°.
Since the diagonals PR and QS of the parallelogram intersect at O, we have:
angle QPO + angle SPO = 180° (sum of angles in triangle POS)
angle QPS + angle SPO = 180° (sum of angles in triangle PQO)
Substituting the values we know, we get:
30° + angle SPO = 180° (1)
30° + angle SPO = 180° (2)
From equations (1) and (2), we get:
angle SPO = 150°
Now, considering the triangle SQR, we know:
angle SQR + angle QRS + angle RSQ = 180° (sum of angles in triangle SQR)
angle SQR + 30° + 30° = 180°
Simplifying, we get:
angle SQR = 120°
Therefore, the answer is (d) 100°.
