ANSWER:
8-4 Trigonometry
Express each ratio as a fraction and as a decimal to the nearest hundredth. 1. sin A
3. cos A
SOLUTION:
The cosine of an angle is defined as the ratio of the adjacent side to the hypotenuse. So,
ANSWER:
SOLUTION:
The sine of an angle is defined as the ratio of the opposite side to the hypotenuse. So,
4. tan A
ANSWER:
2. tan C
SOLUTION:
The tangent of an angle is defined as the ratio of the opposite side to the adjacent side. So,
ANSWER:
