Correction needed (Question:328781.0)

Firstly QTRS is not a quadrilateral; it should be QSTR. Secondly at least put the value of PT in the question.
It is requested to the question-setter to be more serious and accurate while typing the questions. The candidates who are taking the exam, are serious about the tests and they have paid for it.

Question:

In the given figure, QTRS is a cyclic quadrilateral. If PT=5cm, SQ=4cm, PS = 6cm and ∠PQR=63⁰, then what is the value (in cm) of TR?

Options:

Solution:

$\begin{matrix} ∠ P Q R = ∠ P T S = 63 \\ ∠ P R Q = ∠ P S T \\ ∠ Q P R = ∠ S P T (c o m m o n a n g l e) \\ ∴ Δ P Q R ~ Δ P T S \\ T R = a (L e t) \\ = > \frac{P S}{P R} = \frac{P T}{P Q} \\ = > \frac{6}{5 + a} = \frac{5}{6 + 4} \\ = > 12 = 5 + a \\ ∴ a = 7 c m \end{matrix}$
