If `sin A=3/4`, calculate cos A and tan A.

Text Solution

AI Generated Solution

To solve the problem where \( \sin A = \frac{3}{4} \), we need to find \( \cos A \) and \( \tan A \). We will use the definitions of sine, cosine, and tangent in the context of a right triangle. ### Step-by-Step Solution: 1. **Draw a Right Triangle**: - Let's represent angle \( A \) in a right triangle. - Label the opposite side (perpendicular) to angle \( A \) as 3 and the hypotenuse as 4, since \( \sin A = \frac{\text{opposite}}{\text{hypotenuse}} = \frac{3}{4} \). ...
