From the picture,
∠RQS + ∠TQS = ∠RQT
Replacing with data,
(14x + 2) + (11x + 3) = 180
(14x + 11x) + (2 + 3) = 180
25x + 5 = 180
25x = 180 - 5
25x = 175
x = 175/25
x = 7
Then, the measures of the angles are:
∠RQS = 14x + 2
∠RQS = 14(7) + 2
∠RQS = 98 + 2
∠RQS = 100°
∠TQS = 11x + 3
∠TQS = 11(7) + 3
∠TQS = 77 + 3
∠TQS = 80°
