Answer:
1. Given- PQRS is a parallelogram in which <s=75°.
Step-by-step explanation:
To find- <p and <q
Solution- <q=<s {opposite angles of parallelogram are equal} therefore, <q= 75°. Now, PQRS is a parallelogram. so, PQ is parallel to SR. <s+<p = 180 (sum of co-interior angles). 75°+<p = 180°. <p = 180°- 75°= 105°. Hence, <s=75° and <p=105°
