PLEASE HELP What is the missing statement in step 10 of the proof?
Given: ABC
With AB=c, BC=a, AC=b prove: a/ sinA=b/sinB=c/sinC
A. a sin A=b sin B
B. C sin A=b sin B
C. a/sinA=b/sinB
D. b/sinB= c/sinC

answer: (-8,4) are the coordinates of a

step-by-step explanation:

let the side of square abcd is x .

thus the area of square abcd is .

now, by the diagram area of triangle ead= 1/2 × ea × ad = 1/2 × ea × x

( because ad is the side of square)

and, according to the question,

the areas of square abcd and right ead are equal.

⇒

⇒ea=2x

thus, ea: ab=2: 1

therefore, point a divides line segment eb into the ratio 2: 1.

⇒ by sectional formula coordinates of a are,

=

=

=(-8, 4)

thus the coordinates of a are (-8,4)
