The answer of the question is A
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.

Answer: 35
Step-by-step explanation:
Given : A bag contains four red marbles, two green ones, one lavender one, three yellows, and one orange marble.
Total = 4+2+1+3+1=11
To find sets of four marbles include none of the red ones, we need to exclude red marbles when we count the total number of marbles.
Then, the total marbles(exclude red) =11-4=7
Now, the combination of 7 marbles taking 4 at a time is given by :-

Hence, the number of sets of four marbles include none of the red ones = 35
