Can you please help me

This is a 45, 45, 90 triangle.

That means, x is equal to 12, since all 45, 45, 90 triangles are also isosceles, meaning that two of their sides are equal to each other.

To solve for y, we can use the Pythagorean theorem:

12^2 + 12^2 = y^2

288 = y^2

y=12

Let me know if this helps!

step-by-step explanation:

3/10 times, the 5 year old will get a tablet. 5/10 times, the 13 yer old will get a tablet. multiply both fractions to get 15/100 times, both would have a tablet.

the answer is c: divide the arc's degree measure by 360°, then multiply by the circumference of the circle.
