Three houses are mapped on a coordinate grid. Josh’s house is located on Red Street at (–5,–4).
Sarah’s house is located on Green Street at (2,5).
Emma’s house is located on the corner of Red Street and Green Street at (4,–1).
What is the measure of the angle (in degrees) where Red Street and the Green Street intersect?Three houses are mapped on a coordinate grid.

900 degrees

step-by-step explanation:

answer: 12,000

step-by-step explanation: first you ar e supposed to add. then multiply then subtract

the answer is  

a.

28 ft2

step-by-step explanation:

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)
