Explanation: $\sin^2 x + \sin^2(90-x) = \sin^2 x + \cos^2 x = 1$. Pairs: $(1, 89), (3, 87) \dots$. Total terms: $\frac89-12 + 1 = 45$ terms. Total pairs = 22. Middle term is 45 (since sequence $1,3,5...89$, n=45, mid term is 23rd term, which is $2(23)-1 = 45$). Sum $= 22 \times 1 + \sin^2 45^\circ$. Sum $= 22 + (1/\sqrt2)^2 = 22 + 0.5 = 22.5$. Wait, Option A is 22, B is 22.5. However, 89 is the last term. Sequence $1, 3, \dots, 89$. $89 = 1 + (n-1)2 \implies 88/2 = 44 \implies n=45$. $\sin^2 45$ is the unpaired term. Sum = $22(1) + 0.5 = 22.5$.
