Identify sin A as a fraction and as a decimal rounded to the nearest hundredth. HELP PLEASE!! I don't understand.
1 answer:
Answer:
sin A = opp / hyp = 0.82
Step-by-step explanation:
The sine function is defined as the ratio of "opposite side" to "hypotenuse."
In the given triangle, sin A = opp / hyp = 10.3 / 12.6 = 0.82 (to the nearest hundredth). That's all you have to do here.
The cosine function is the ratio of "adjacent side" to "hyp." In the given triangle, the side adjacent to angle A has length 7 .2. Thus,
cos A = adj / hyp = 7.2 / 12.6 = 0.57 (to the nearest hundredth).
