Answer: $4\sqrt{3}-\sqrt{5}$

Step by step:

$2\sqrt{5}+4\sqrt{3}-3\sqrt{5}=4\sqrt{3}-\sqrt{5}$ This is the simplest form of this radical.

To solve for P(QIR) we use the formula:
P(QIR)=[P(Q∩R)]/P(R)
But from the diagram:
P(Q∩R)=3/22
P(R)=7/22
hence
P(QIR)=3/22÷7/22=3/7

Those two angles have the same measure, so you have

$2k+11=131 \iff 2k=120 \iff k=60$
