Answer:

Yes, Pythagorean theorem

Step-by-step explanation:

Yes, as by doing the Pythagorean theorem, a^2+b^2=c^2 you can confirm that it is.

8^2+15^2=17^2

64+225=17^2

289=17^2

(square root both sides)

17=17

Aster sold 18 oranges if this are 12% of her total oranges how many oranges are not sold

WITCHER [35]

Answer:

Step-by-step explanation:

So 18 oranges are 12 percent of her total oranges. You can use Ratio to solve this.

O : P

18 : 12 P = Percentage O = Orange

1.5 : 1

150 : 100

All I did was make the percentage one by dividing both numbers by 12. This makes it 1.5 oranges per percent. Times 1.5 with 100 to make it 100 percent.

Think About a Plan Write an indirect proof.

Alekssandra [29.7K]

1) Either $\ell \parallel p$ or $\ell$ ∦ $p$ (only two possibilities)

2) Assume $\ell \parallel p$ (one of two possibilities)

3) $\angle 1 \cong \angle 2$ (if two parallel lines are cut by a transversal, the corresponding angles are congruent)

4) But $\angle 1$ is not congruent to $\angle 2$ (given)

5) So $\ell$ ∦ $p$ (only other possibility)
