Given an equilateral triangle that has an area of 1959 cm2. What is the length of its sides?
Nina [5.8K]
Equilateral
equi means equal
lateral means sides

all sides are equal
triangle has 3 sides

perimiter=side1+side2+side3
side1=side2=side3


area=1/2 times base times height
base=side
draw a line down the middle of te tiangle so you get 2 right triangles side by side
1/2base is one leg
base is hypotonuse
height is unknown
equilateral means that it is a 30-60-90 triangle with  hypotonuse equal to 2x, height=x√3, bottom is x
1/2 times base times height=1959
1/2 times x times x√3=1959
multiply both sides by 2
(x^2)√3=3918
divide both sides by √3
x^2=3918/√3
square root both sides
x=47.5611
side=hypotonuse=2x
2x=2*47.5611
side=95.12222


legnth of each side is 2\sqrt{ \frac{3918}{ \sqrt{3} } }cm or about 95.12222 cm

The total cost of hiring paul the plumber is a function of the required number of hours needed to complete the repair. Paul char
DiKsa [7]

Paul surely charges 75 dollars, and then he adds 40 dollars per hours. This means that the expression for the money he asks is

m = 75+40h

where m is the amount of money and h is the number of hours.

Since h can be at most 8, this is the case that generates the highest money, so if we plug h=8 we have

m = 75+40\cdot 8 = 75 + 320 = 395
