The answer is C because AO and BO are equal. And with AO being three times the length of CO, BO should be the length of DO
Answer:
Its C im pretty sure. Also loveee your pfp!
Answer:
120
Step-by-step explanation:
all complementary angles should add up to 180 degrees
Answer: 
Step-by-step explanation:





A rotation 270° counterclockwise about the origin is the same as rotation 90° clockwise about the origin and has a rule:
(x,y)→(y,-x).
Then:
- D(−2,4)→D'(4,2)
- E(4,7)→E'(7,-4)
- F(10,3)→F'(3,-10)
- G(8,0)→G'(0,-8)
Answer: the coordinates of vertices of quadrilateral D′E′F′G′ are D'(4,2), E'(7,-4), F'(3,-10), G'(0,-8).
