Complete the following statements to prove that ∠ikl and ∠jld are supplementary angles.
it is given that ∠eij ≅ ∠gji.
also, ∠eij ≅ ∠ikl and ∠gji ≅ ∠jlk, as they are corresponding angles for parallel lines cut by a transversal.
by the definition of congruent angles, m∠eij = m∠gji, m∠eij = m∠ikl, and m∠gji = m∠jlk.
so, m∠ikl = m∠jlk by the .
angle jlk and ∠jld are supplementary angles by the , so m∠jlk + m∠jld = 180°.
by the , m∠ikl + m∠jld = 180°.
therefore, ∠ikl and ∠jld are supplementary angles by definition.

sorry i just need to anwers this to get points

step-by-step explanation:

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)

1. 523.33 cubic inches

3. 17.41.

4. 16.49

i think this should be your answer

hope i
