You will have 4 pieces.
<u><em>Explanation</em></u>
Suppose, the number of pieces is 
As each piece must be 
of a square and you have initially 
of a square, so the equation will be.....
So, you will have 4 pieces.
Answer:
To find the equation of the line parallel to the graph, first of all find the slope of the graph by making y the subject of the formula and comparing the resulting equation with y = mx + c , knowing fully well that m stands for the slope.
So, from the equation of the graph give, y = 4x/5 +1/5, therefore the slope is 4/5. For a line to be parallel to the graph then they must have the same slope, to find the equation of the line at the given point, then we use the formula
y - y1 = m ( x - x1 )
y - 3 = 4/5 ( x - 1 )
multiply through by 5
5( y - 3 ) = 4 ( x - 1)
5y - 15 = 4x - 4
5y - 4x = - 4 + 15
so, 5y - 4x = 11 is the equation

Answer:
Option B ⇒ 
Step-by-step explanation:
Cos B = adjacent/hypotenuse
adjacent = 12
hypotenuse = 13
∴ cos B = 12/13
The answer is option B
Answer:
a) X = 65°
b) Y = 71°
c) Z = 44°
Step-by-step explanation:
a) X is a vertical angle with the one marked 65°, so has that same measure.
b) Y is an opposite interior angle with the one marked 71° where the transversal between angles Y and Z crosses the parallel lines. That makes it have the measure 71°.
c) Z is the third angle of a triangle with the other two angles being 65° and 71°, so it is 180° -65° -71° = 44°. (The sum of angles of a triangle is 180°.)
