Example 1: Find Sin A and Sec A, if 15 cot A = 8. Solution: Given that 15 cot A = 8 Therefore, cot A = 8/15. We know that tan A = 1/ cot A Hence, tan A = 1/(8/15) = 15/8. Thus, Side opposite to ∠A/Side Adjacent to ∠A = 15/8 Let BC be the side opposite to ∠A and AB be the side adjacent to ∠A and AC be the hypotenuse … See more The notes for trigonometry class 10 Maths is provided here.
