1.The coordinates of the vertices of △RST are R(−4, −1) , S(−1, −1) , and T(−4, −2) .
1 answer:
RS points east; R'S' points north, so there has been a rotation 90° CCW.
After that rotation, point S would be at (1, -1). It is actually at (1, 1), so has been shifted 2 units upward.
A sequence that does the desired mapping is
- c. rotation of 90° CCW about the origin
- b. translation 2 units up

Answer:
371.2
Step-by-step explanation:
Because AC is a diameter we can find the 180/3 = x
giving us the x= 60
Then that arc AB = 120
