1. Plot the points in the coordinate axes as in the attached picture.

2.  The trapezoid is isosceles. This can be easily checked by calculating WZ and XY by the Pythagorean theorem. Or simply by the picture.

    The midpoint of W and X is at (1, 2)
    The midpoint of Z and Y is at (1, -1)

    the line of symmetry is the line passing through these 2 midpoints. This line is the vertical line through x=1.

Answer: axis of symmetry: line with equation x=1
              justification: the pairs W,X and Z,Y are symmetrical with respect to this line

What is the value of x? A.86 B.60 C.52 D.26
Nadya [2.5K]

   First of all in order for us to figure out what angle x is we need to find the formula for finding that specific type of angle.

Formula is...

x = (far arc - close arc) ÷ 2

Now we just need to plug in.

x = (172° - 52°) ÷ 2 =

x = 120° ÷ 2 = 60°

Your answer: x = 60°

Good Luck! :)

FOR 12 POINTS I NEED HELP ASAP! Consider the system of linear equations. 5 x + 10 y = 15. 10 x + 3 y = 13 To use the linear comb
Romashka [77]

Answer:

Do you mean which equation should the 5x+10=15 be multiplied to?

it would be -2

Step-by-step explanation:

This is because 5 times -2 is -10

and so when you add the (now) x value of the first equation to the x value of the second equation, it gets 0

which makes it eliminated!

-10x+10x=0
