SOLUTION: In the figure, S is the interior of angle PQR. If the measure of angle PQR is equal to 50 and the measure of PQS is 40 less than the measure of RQS, what is the measure of the angl
Let x be the measure of the angle PQS, in degrees.
Then the measure of the angle RQS is (x+40) degrees.
From the condition, you have THIS equation
x + (x+40) = 50.
It implies
2x = 50-40 = 10 degrees;
hence,
x = 10/2 = 5 degrees. ANSWER
