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
cm or about 95.12222 cm

The values of (x,y)=(4,4). In terms of x, the value y(x)=8-x, If the given equation is and
.
Step-by-step explanation:
The given is,
...............................(1)
...............................(2)
Step:1
Solution can be obtained by Elimination method,
Equation (1) is multiplied by (-1) ( Eqn (1) × -1 )
..............................(3)
Substrate the equation (1) and equation (3),
( - )
we can cancel the minus because it is available in both sides,
x = 4
From the value of x, Equation (2) becomes,
(Value of y in terms of x)
Where, x = 4
Step:2
Check for solution,
.....................................(2)
Substitute the values of x and y,
4 + 4 = 8
8 = 8
Result:
The values of (x,y)=(4,4). In terms of x, the value y(x)=8-x, where x=4. If the given equation is and
