Answer:
OQ = 16
PR = 32
m<QRS = 90 degrees
Step-by-step explanation:
Since we know that PQRS is a rectangle, we can use its properties to find that:
OQ, OS, OR, and OP are equivalent, meaning that they all equal 16. Therefore, OQ = 16.
PR = OR + OP, meaning that 16 + 16 = PR, meaning that PR = 32.
And finally, m<QRS = 90 degrees because all corner angles in a rectangle are right angles.
I hope this helps!
