The length of b and angle B and C are 3cm, 45 degrees and 79 degrees respectively.
<h3>How to determine the parameters</h3>
To determine the angles and length of sides, we use the sine rule
The sine rule is thus:
Given;
Let's find angle C
cross multiply
0. 682 × 3. 6 = sin C × 2. 5
sin C = 2. 4552/ 2. 5
C = 
C = 79°
To find length of b
substitute the values
b = 2. 59 cm
b = 3cm
To find angle B, we have
cross multiply
0. 682 × 2. 59= sin B × 2. 5
sin B = 0. 7065
B = 45°
Hence, the length of b and angle B and C are 3cm, 45 degrees and 79 degrees respectively.

Millions are after hundred thousands.
Answer: c) 300 copies
Step-by-step explanation:
Let x represent the number of copies that you must sell to break even.
You decide to market your own custom computer software. You must invest 3,255 for computer hardware,and spend 2.90 to buy and package each disk. This means that the total cost of producing each software would be
3255 + 2.9x
If each program sells for $13.75, it means that the total revenue from selling each software would be
13.75x
In order to break even, total cost would be equal to total revenue. Therefore,
3255 + 2.9x = 13.75x
13.75x - 2.9x = 3255
10.85x = 3255
x = 3255/10.85
x = 300 copies
