Answer:

Step-by-step explanation:
<h3>to understand this</h3><h3>you need to know about:</h3>
<h3>tips and formulas:</h3>
- (a+b)³=a³+3a²b+3ab²+b³
- a³+b³=(a+b)(a²-ab+b²)
<h3>let's solve:</h3>





and
we are done
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.
