Q3 of 23 Page 1

Solve sub-questions:

In the following figure, ray PT is the bisector of ∠QPR Find the value of x and perimeter of ∠QPR.


In Δ PQR, PT is the bisector of ∠P

∴


⇒


⇒ 4PR = 18


⇒PR = cm


⇒ QR =QT +TR


⇒ QR = 4+5 = 9cm


⇒ Perimeter of Δ PQR =PQ+QR +PR


⇒ 3.6+9+4.5 = 17.1cm


⇒ Perimeter of Δ PQR = 17.1cm
