    If sinAo┬а= (тИЪ3/2), then find the value of

    (sin245o┬а+ cos230o) ├Ч A ├╖ 5 given that 0 < A < 90.
    A 10 Correct Answer Incorrect Answer
    B 15 Correct Answer Incorrect Answer
    C 25 Correct Answer Incorrect Answer
    D 8 Correct Answer Incorrect Answer

    Solution

    A = sin-1 (тИЪ3/2) = 60 sin245o┬а+ cos230o X A ├╖ 5 = {(1/тИЪ2)2 + (тИЪ3/2)2} x 60 ├╖ 5 = {(1/2) + (3/4)} ├Ч 12 = (5/4) ├Ч 12 = 15
