Here is ur answer............
7 pie/8+pie/8=pie
5pie/8+3pie/8=pieso,
(cos^2) pie/8+(cos^2) 3pie/8 +(cos^2)(pie-3pie/8)+(cos^2)(pie-pie/8)
(cos^2)pie/8+(cos^2)3 pie/8+(cos^2)pie/8+(cos^2)3pie/8
2{(cos^2)pie/8+(cos^2)3pie/8}
pie /8+3pie/8=pie/2
so ,
2{(cos^2)pie/8+(cos^2)(pie/2-pie/8)}
2{(cos^2)pie/8+(sin^2)pie/8}      (sin^2 theta + cos^2 theta=1)
2(1)
2
 so, answer is 2
hope it helps uh....
