Final answer:
In a parallelogram, opposite angles are congruent, so if one angle is 70°, the angle opposite to it is also 70°.
Step-by-step explanation:
The question asked is: If (QRST) is a parallelogram and (mangle ZQRS = 70°), then (mangle TQR) is:**
The options are: A) 70° B) 110° C) 70° less than a right angle and D) 110° less than a right angle
If (QRST) is a parallelogram and (mangle ZQRS = 70°), then mangle TQR must also be 70°. This is because in a parallelogram, opposite angles are congruent (equal). Since QRS is 70°, angle TQR, which is opposite to it, must also be 70°. Therefore, the correct answer is A) 70°.
