He/she forgot that 8^2=64 not 16, and 7^2=49 not 14. As a result, the correct answer is:
a^2+b^2=c^2
7^2+b^2=8^2
49+b^2=64
b^2=15
b≈3.9 cm. Hope it help!

Given: Lines p and q are parallel and r is a transversal.
qwelly [4]

The statements that would complete the proof where ∠2 ≅ ∠7 by the transitive property are:

∠2 ≅ ∠3

∠3 ≅ ∠7

<h3>What is the Transitive Property?</h3>

The transitive property states that if x = y, and y = z, then x = z.

From the image given below, we have:

∠2 ≅ ∠3 because they are vertical angles which must be congruent.

∠3 ≅ ∠7 because corresponding angles are congruent.

Applying the transitive property, we can state that: ∠2 ≅ ∠7.

Therefore, the statements that would complete the proof are:

  • ∠2 ≅ ∠3
  • ∠3 ≅ ∠7

Find an nth degree polynomial function with real coefficients satisfying the given conditions.
damaskus [11]

Step-by-step explanation:

Our roots are 3, and i so our roots form

will be

(x - 3)(x - i)

Since i is one root, it conjugate, must be the other.

so we have

(x - 3)(x - i)(x + i)

Simplify

( {x}^{2}  + 1)(x - 3)

{x}^{3}  - 3 {x}^{2}  + x - 3

So the function is

x {}^{3}  - 3 {x}^{2}  + x - 3
