Answer:

QR is tangent to circle P at point Q

=> RQP = 90 deg

=> RQP is right triangle.

=> Applying Pythagorean theorem for right triangle RQP:

    QP^2 + QR^2 = RP^2

=>4^2 + QR^2 = RP^2

=> Option A is correct.

(4^2 + (4*[tex]\sqrt{3}[/tex])^2 = 16 + 48 = 64 = 8^2)

=> Option C is correct.

(4^2 + 3^2 = 16 + 9 = 25 = 5^2)

=> Option D is correct

(4^2 + 2^2 = 16 + 4 = 20 = (2[tex]\sqrt{5}[/tex])^2)

Hope this helps!
