Which of these descriptions of a triangle ABC are directions that can be followed to draw exactly one shape. 9a) Line AB is 2.5 in. LIne AC is 2 in. Angle B is 40 degrees

9b) Line AB is 2.5 in. Line AC is 1 in. Angle a is 40 degrees

9c) Line AB is 2.5 in. Angle B is 60 degrees Angle A is 40 degrees

9d) Line AB is 2.5 in. Angle B is 60 degrees Angle A is 130 degrees

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)
