Since this is a right triangle, you can use the pythagorean theorem, $leg^2+leg^2=hypotenuse^2$ , to find XY. Since we know that 15 and 17 are our legs and that XY is the hypotenuse, we can solve it as such:

$15^2+17^2=XY^2\\ 225+289=XY^2\\ 514=XY^2\\ \sqrt{514}=XY$

In short, XY is √514, or 22.67 rounded to the hundreths, units long.

Please help!! I need to go to the next question!

tino4ka555 [31]

Given:

The inequality is:

$3t+1\leq 5$

To find:

The graph of the given inequality.

Solution:

We have,

$3t+1\leq 5$

Subtract both sides by 1.

$3t\leq 5-1$

$3t\leq 4$

Divide both sides by 3.

$t\leq \dfrac{4}{3}$

The value of t is less than or equal to $\dfrac{4}{3}$ .

Since $t\leq \dfrac{4}{3}$ , it means $\dfrac{4}{3}$ is included in the solution, therefore there is a closed circle at $t=\dfrac{4}{3}$ and an arrow approaches to left from $t=\dfrac{4}{3}$ .

Therefore, the correct option is A.
