Step-by-step explanation:
Given,
2sin²Q - 2√2sinQ + 1 = 0
2sin²Q - 1√2sinQ - 1√2sinQ + 1 = 0
1√2sinQ(1√2sinQ - 1) - 1(1√2sinQ - 1) = 0
(1√2sinQ - 1)(1√2sinQ - 1) = 0
(1√2sinQ - 1)² = 0
(1√2sinQ - 1 = 0
sinQ = 1/1√2
sinQ = 1/√2
sinQ = sin45°
Comparing both sides,
Q = 45°
Therefore, the answer is C) 45°
