Question
In $11-22,$ solve each triangle, that is, find the measures of the remaining three parts of the triangle to the nearest integer or the nearest degree.In $\triangle P Q R, p=12, \mathrm{m} \angle Q=80,$ and $\mathrm{m} \angle R=30$
Step 1
We can find the measure of angle $P$ using the fact that the sum of the interior angles in a triangle is $180^{\circ}$. So, we have \[\mathrm{m} \angle P + \mathrm{m} \angle Q + \mathrm{m} \angle R = 180^{\circ}.\] Substituting the given values, we Show more…
