from the point of interior of an equilateral triangle. perpendiculars are drawn on three sides the length of the perpendicular are 10 cm, 12 cm and 7 cm find the area of the triangle ​

r and t.

both are 64 degrees.

it would be a on edgenuit y

the diagram below is your final answer

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)

answer: 5/2     2 1/2

step-by-step explanation:

5/2              

5 goes into 2 two times so its 2 and 1/2
