Triangle xyz has vertices x(1, –1), y(3, 4), and z(5, –1). nikko rotated the triangle 90° counterclockwise about the origin. what is the correct set of image points for triangle x’y’z’?

The coordinates of X'Y'Z' are X'(1,1), Y'(-4,3), and Z'(1,5).

The triangle XYZ given with the coordinates of vertices that are as follow:

X = ( 1, - 1 )

Y = ( 3, 4 )

Z = ( 5, - 1 )

We need to determine the coordinates of the vertices of the triangle that is obtained by rotating XYZ triangle 90° counterclockwise about the origin.

The value of abscissa and ordinate gets interchanged with a negative sign in abscissa when a figure is rotated 90° counterclockwise about the origin.

Shifting of the coordinates are as follow:

( x, y ) can be interchanged to ( -y, x ) after rotation.

Thus, the coordinates of X'Y'Z' are X'(1,1), Y'(-4,3), and Z'(1,5).

answer: i'm not going to give you the answer, but some hints to work it out.

step-by-step explanation: so, if there is a straight line that means that the line angle is 180°. so we subtract the 2 angle measures provided, (15 and 38) from 180. so the answer is 180 - (38 + 15). (you have to solve the equation)

the correct answer is $7.38
