Answer:
QR = 16 units
Step-by-step explanation:
Given that ΔPQR is right with hypotenuse QR
We can apply Pythagoras' theorem to find QR
QR² = 8² + (8)²
= 64 + 192
= 256
Take the square root of both sides
QR = = 16 units
Answer:
i think 4 is correct
Step-by-step explanation:
The answer is c. circumcenter
