In Delta PQR, angle PQR = 90^(@), "seg" QM bot hyp PR, PM = 16 and RM = 9 then QM…….

In the adjoining figure, if PQ = 6, QR = 10, PS = 8, then find TS.

Solve the following sub question : in the adjoining figure, seg PS bat side QR. If PQ = a, PR = b QS = c and Rs = d then complete the following activity to prove that (a + b) (a - b) = (c + d) (c - d) Proof : In Delta PSQ angle PSQ = 90 ^(@) square^(2) = PS^(2) + square^(2) PS^(2) = square^(2) - square^(2) In Delta PSR, angle PSR = 90^(@) square^(2) = PS^(2) + square^(2) PS^(2) = square^(2) - square^(2) = square^(2) - square^(2) a^(2) - c^(2) = b^(2) - d^(2) a^(2) - b^(2) = C^(2) - d^(2) square xx square = square xx square
