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).

Complete question
Use the grouping method to factor the polynomial below completely.
x³ + 2x² + 5x+10
O A. (+5)(x+2)
O B. (x²+5)(x+2)
O C. (+5)(x+5)
O D. (+5)(x+5)
Answer:
O B. (x²+5)(x+2)
Step-by-step explanation:
From the above question, we are given the polynomial:
x³ + 2x² + 5x+10
Using the grouping method to factor the polynomial
= x³ + 5x +2x² + 10
= (x³ + 5x) +(2x² + 10)
= x(x² + 5) +2(x² + 5)
= (x + 2) (x² + 5)
Therefore, the factor of the polynomial x³ + 2x² + 5x + 10 is (x + 2) (x² + 5).
