So lets ABCD are the sides of the square and AB=CD, AC=BD and the Angle ABC = 90 so therefore by making a diagonal we can use the SAS or SSS congruency for two triangles, so we can prove two triangles are equal and that is why the shape is square.
The angles inside a trapezoid add up to equal 360 degrees
X = 360-90-90-75 = 105 degrees.
Minus 9x from both sides
-3y=-9x+12
divide both sides by -3
y=3x-4
A recursive formula designates the starting term, a1, and the nth term of the sequence, an , as an expression containing the previous term (the term before it), an-1. ... Find a recursive formula. This example is an arithmetic sequence (the same number, 5, is added to each term to get to the next term).
ANSWER:
0
EXPLANATION:
3/7=0.4
if the number to the right of decimal point is 0.5 and higher,then add 1 to the left of the decimal point.
if the number to the right is less than 0.5,leave the number to the left and remove the digit to the right decimal point.
