The equation is 2y = x-3

Step-by-step explanation:

Equation of WX is;

2x + y = -5

Can be written as;

y = -5 -2x

compare it with standard form

y = mx + c

where m is slope and c is intercept.

Slope of the line is thus -2

The second line is perpendicular to WX

this means that the product of their slopes is -1

Mathematically;

-2 * slope of second line = -1

Slope of second line is -1/-2 = 1/2

Now we use the point slope form to get the equation of that second line

Mathematically;

y-y1 = m(x-x1)

y-(-2) = 1/2(x-(-1))

y + 2 = 1/2(x + 1)

2(y + 2) = x + 1

2y + 4 = x + 1

2y = x + 1-4

2y = x-3

step-by-step explanation:

two pairs of adjacent sides are of equal length. this implies that one diagonal divides the kite into congruent triangles, and so the angles between the two pairs of equal sides are equal in measure. it also implies that the diagonals are perpendicular.

i believe it is 0.1m because the measurement of 30.4m limits how precise you can be

you can only be as precise as the least precise measurement
