Question
One angle of a triangle is twice as large as another. The measure of the third angle is $20^{\circ}$ more than that of the smallest angle. Find the measure of cach angle.
Step 1
According to the problem, one angle is twice as large as another, so we can denote the second angle as $2Q$. The third angle is $20^{\circ}$ more than the smallest angle, so we can denote it as $Q + 20^{\circ}$. Show more…
