Question

In ∆PQR, ∠Q ≅∠R. If PQ = 10x – 14,
PR = 2x + 50, and RQ = 4x – 30, what is the length of ?

Answer 1

RQ = 2cm (whatever units)

Explanation:

∠Q = ∠R (this means that the triangle is isosceles because there are two angles that are the same)

Since these angles are the same, the sides that are opposite these angles must be the same as well.
