Passage / Comprehension

In tetrahedron $PQRS, PQ = 4$ . Plane $P_{1}$ is perpendicular to $PQ$ . The feet from $P, R, S$ to $P_{1}$ are $P^{'}, R^{'}, S^{'}$ , and area $[P^{'} R^{'} S^{'}] = 15$ .

If the distance of $S^{'}$ from plane $PQR$ is 5, find the distance of $R$ from line $PQ$ .

Options:

Answer:

Solution:

In the same coordinates the condition gives $p = 5$ ; since $b p = 30, b = 6$ , which is the distance from $R$ to $PQ$ .
