Which statement verifies that triangle wxy is a right triangle?

the slopes of wx and yw are opposite reciprocals.
the slopes of wx and xy are opposite reciprocals.
the slopes of xy and wx have opposite signs.
the slopes of xy and yw have the same signs

The statement is slope of WX and YW are opposite reciprocals

Step-by-step explanation:

Given the graph in which triangle is shown

we have to choose the statement that verifies that triangle WXY is a right triangle.

Coordinates of W, X and Y are

W=(-2,3)

X=(2,1.4)

Y=(-4,-2)

To verify the triangle WXY a right triangle, we have to find the slope of these lines

We see slope of WX and YW are opposite reciprocals that means these two lines are perpendicular which verifies that triangle WXY is a right triangle.

Hence, option 1 is correct

9.55 degrees.

step-by-step explanation:

the given angle is

1 cycle is equal to 2π radians. so 4π will be equal to two cycles.

5.166667π-4π = 1.166667π

hence, this angle goes a little more than negative x axis.

1.166667π-π= 0.166667π

hence, the reference angle is 0.166667π radians.

1 radian = 57.2958 degrees

now, in degrees, this should be equals to 9.55 degrees.
