If sin A = 7/9. Find Cos A * Cot A |
|
Answer» Answer: 32/63 Explanation: sin = P/H Sin A=7/9 it means 7 is perpendicular and 9 is the hypotneuse. Now we will have to find base by using pythagorean theorem H^2 = P^2+B^2 9×9 = 7×7 + B^2 81=49+B^2 81 - 49 = 32 =B^2 root 32 = base COS = B/H Cos A = root 32/9 cot = B/P Cot A = root 32 / 7 now cos A×Cot A = root 32 /9×root 32/7 = 32/63 |
