Quadrilateral ABCD has the following coordinates: A. (1,3)
B. (8,0)
C. (9,8)
D. (2,7)
Rotate the shape 90° clockwise.
Identify the coordinates for ABCD
A’ ( , )
B’( , )
C’( , )
D’ ( , )

A¹ (3 , -1) , B¹(0,-8) , C¹(8,-9) , D¹(7,-2)

Step-by-step explanation:

Explanation:-

Given coordinates are

  A(1,3) ,B(8,0) ,C( 9,8) ,D(2,7)

The coordinates are rotating the shape 90° clockwise then the transformed to (x,y)→ (y ,-x)

The new coordinates

A(1,3) → A¹ (3 , -1)

B(8,0) →  B¹(0,-8)

C(9,8) →  C¹(8,-9)

D(2,7) →   D¹(7,-2)

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
