What’s the value of X here in this equation?

Step-by-step explanation:

The sum of the interior angles of a triangle is 180 degrees.

5x + 2 + 2x - 8 + 39 = 180

7x + 33 = 180

Subtract 33 to both sides

7x = 180 - 33

7x = 147

Divide both sides by 7

x = 147 / 7

x = 21

Hope this helped!

(-5,-28)

i graphed to on desmos.

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)
