What is the inverse of the conditional statement? If a polygon has five angles, then it is a pentagon.

If a polygon is a pentagon, then it has five angles.
If a polygon is not a pentagon, then it does not have five angles.
If a polygon does not have five angles, then it is not a pentagon.
If a polygon has five angles, then it is not a pentagon.

step-by-step explanation:

60: 45 =12: 9 =4: 3 so the answer is 4: 3

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)
