Write a rule to describe the transformation. A. reflection across y=x
B. rotation 90º clockwise about the origin
C. rotation 180º about the origin
D. rotation 90º counterclockwise about the origin

C. rotation 180º about the origin

Step-by-step explanation:

Given

Quadrilaterals GWVY and G'W'V'Y'

Required

Describe the transformation rule

Pick points Y and Y'

The above obeys the following rule:

When a point is rotated by 180 degrees, the rule is:

Hence, (c) is correct

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
