Question

9In a quadrilateral PQRS, the bisectors of Q and R meet at T. Find the measure of QTR, if P = 150° and S = 50​

Answer 1

Answer:

R.E.F image

y=Px−Qx2

we know that,

y=xtanθ−2U2cos2θgx2

So comparing,

P=tanθ

Q=2U2cos2θq

cosθ=P2+11

sinθ=P2+1P

U2=2θg(P2+1)

(i) Range =g2U2sinθcosθ

=2×g2θ×g(P2+1)×(P2+1)P

⇒P/Q

(iii) max height =2gU2sin2θ
