Answer:
∠RQS = 100°
Explanation:
The angles 5x + 5 and 11x - 65 form a linear pair. That is they sum to 180°
Sum the 2 angles and equate to 180, that is
5x + 5 + 11x - 65 = 180
16x - 60 = 180 ( add 60 to both sides )
16x = 240 ( divide both sides by 16 )
x = 15
∠RQS = 11x - 65 = (11 × 15) - 65 = 165 - 65 = 100°
