What is the algebraic rule for a figure that is rotated 270° counterclockwise about the origin? . a) ro,–270°(x, y) → (–y, x). b) ro,–270°(x, y) → (x, –y). c) ro,270°(x, y) → (–x, –y). d) ro,270°(x, y) → (y, –x).

The aswer is D.) RO,270°(x, y) → (y, –x)

(from Edgeneuity).

Hope this helps! :D

Step-by-step explanation:

step-by-step explanation :

we know that

the measurement of the outer angle is the semi-difference of the arcs which comprises

in this problem

m< xzy is the outer angle

substitute the values

the measure of angle xoy is equal to

> by central angle

substitute the value

hope this : )
