Theorem of cosine:
a²=b²+c²-2bc(cos α) ⇒cos α=-(a²-b²-c²) / 2bc
In this case:
a=15 cm
b=10 cm
c=5 cm
cos α=-(15²-10²-5²) / 2*10*5
cos α=-100 / 100
cos α=-1
A=arc cos -1=180º This is impossible, because:
A+B+C=180º; then B=C=0º This is impossible for make a triangle (B>0 and C>0 if we want to make a triangle).
Therefore: it is not possible can make a triangle with side lengths of 5 cm, 10 cm and 15 cm.
Area of Rectangle = length times width
lets say length = 2x-4
width = x+5
Note: you can switch these around, width could be 2x-4 and length could be x+5, it doesnt matter.
With that being said:
length * width = area
(2x-4)(x+5)=area

Answer:
His monthly sales goal if he budgets $3750 as his monthly income is $15000.
Step-by-step explanation:
From the information given, the formula to calculate the salary that Ron earns would be:
Total salary=1500+0.15*(monthly sales)
Now, you can replace the total salary and he budgets $3750 as his monthly income and solve for the monthly sales:
3750=1500+0.15*(monthly sales)
3750-1500=0.15*(monthly sales)
monthly sales=2250/0.15
monthly sales=15000
According to this, the answer is that his monthly sales goal if he budgets $3750 as his monthly income is $15000.
