X=29 and y=10
You would isolate one of the variables and then plug the expression into the other equation to find the value of one variable. Then you would plug this value into the other equation to determine the value of the remaining variable.
Answer:
168 employees
Step-by-step explanation:
5:3
63 / 3 = 21
5*21=105
105+63=168
Answer:12
Step-by-step explanation:
The length of b and angle B and C are 2. 9cm, 44. 9 degrees and 79. 11 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;
- a = 2. 5cm
- c = 3. 6cm
- ∠A = 43°
Let's find angle C
cross multiply
0. 682 × 3. 6 = sin C × 2. 5
sin C = 2. 4552/ 2. 5
C = 
C = 79. 11°
To find length of b
b = 
substitute the values
b = 
b = 
b = 
Take square root
b = 2. 59 cm
To find angle B, we have
cross multiply
0. 682 × 2. 59= sin B × 2. 5
sin B = 0. 7066
B = 
B = 44. 9 °
Thus , the length of b and angle B and C are 2. 9cm, 44. 9 degrees and 79. 11 degrees respectively.
