Identify sin a as a fraction and as a decimal rounded to the nearest hundredth. i don't understand.

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).

the correct answer is d

hope this

it is x equals 3   plese mark me really need it
