Triangle PAB and square ABCD are in perpendicular planes.Given that `PA = 3, PB = 4, and AB = 5` whats is PD?

ABCD is a square. P is a point inside the square such that PA = 3, PB = 7, PD = 5 . Then area of square ABCD is …………..

Find PB, given that PA=15,PC=20,PD=7, and ABCD is a square.

In the given figure PA=6, PB=4 and PC=8. Find PD.

In the given figure PA=6, PB=4 and PC=8. Find PD.

There is a point P in a rectangle ABCD, such that PA = 4, PD = 5, PB = 8, find PC.

In the given Fig. 5, from an external point P, a tangent PT and a secant PAB is drawn to a circle with centre 0. ON is perpendicular on the chord AB. Prove that PA.PB = PT^(2) ?.

If P be a point in the interior of equilateral triangle ABC such that PA=3,PB=4 and PC=5 then find a.

ABCD is a parallelogram DP is perpendicular to AB. Given BD = 5 cm, AP = 3 cm. and area of Delta ADP = 6 sq. cm, find the perimeter of ABCD.

PAB and PCD are two secants to a circle. If PA = 10 cm, AB = 12 cm and PC = 11 cm, then what is the value (in cm) of PD?
