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
It is 395.3 use calculators or do the division out of paper
Answer:
9 songs
Explanation:
Given:
The slideshow is 31 whole number 1/2 minutes long
convert to an improper fraction
31×2+1/2 = 63/2
The songs are each 3 whole number 1/2 minutes long
convert to an improper fraction
3×2+1/2 = 7/2
To find the number of songs that Marcus is picking to play during a slideshow, divide the slideshow by the long of one song
(63/2) / (7/2)
= 9 songs.
