Complete question:
What are the x- and y- coordinates of point E, which partitions the directed line segment from
into a ratio of 1 : 2.
Answer:
(C) (-2,5)
Step-by-step explanation:


m=1, n=2


The x- and y-coordinates of the point E is (-2,5)
Answer:
C
Step-by-step explanation:
A) not true. Sin A = some decimal
Cos 720 = 1
D) That means that d is not true either. not true
B) Sin55 = cos55 is not true either only sin(45) = cos(45) is true. So B is not true.
That leaves C. I think if you check it, you'll find it is right. sin(A) = cos(90 - A)
(q ° r) = -32
(r ° q) = 101
