7-69.

Beatriz notices that two angles in $ΔPQR$, shown at right, have the same measure.

1. Based on this information, what statement can you make about the relationship between $\overline{QP}$ and $\overline{QR}$ ?

The base angles have equal measure. What kind of triangle is this?

The stated sides must have equal length.

2. If $QP = 5$ mm, what is the length of $\overline{PR}$ ?

Calculate the measure of the missing angle.

Can you use the Law of Sines to find your solution?

$≈ 6.67$ mm
