Data
Perimeter =32x - 12.8
Formula to calculate the perimeter of a square
Perimeter = 4 length of the side
Calculate the length of 1 side
4 length of the side = 32x - 12.8
length of the side = (32x -12.8) / 4
Simplification
length of the side = 8x - 3.2
Another way to represent the perimeter = 4(8x - 3.2)
See the picture below
Answer:
x=30, <A=60, <C=30
Step-by-step explanation:
A triangle always has its total angles added up to 180 degrees, so we can set up the following equation:
90+2x+x=180
90+3x=180
3x=90
x=30
Since x=30, this means <C is 30 degrees. For <A, it's twice as much as <C, so 2*30=60.
So x=30, <A=60, <C=30

Simplify 2.8y + 6 + 0.2y to 3y + 6
subtract 3y from both sides
simplify 5y - 15 - 3y to 2y - 15
add 15 to both sides
simplify 6 + 15 to 21
divide both sides by 2
switch sides
