B) in their last 50 matches, they have drawn 10 matches, lost 5 and won the rest. Sam claims 'the probability that plaza United will win this match is 0.7' show calculations to support Sam's claims. x

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)

the answer is -1 1/5, also a

-lavira : )

-3.5 is the distance.

i've had this question so choose the one in the absolute value sign.
