Answer:
3
Explanation:
the triangle is a right triangle, meaning that we can use the pythagorean theorem to find a hypotenuse that will satisfy both Rs. if we use 3 as the radius, we get the hypotenuse as 2 + 3 = 5, where one leg is 3 and one is 4.
![\sqrt{} 3 {}^(2) + 4 { }^(2) = 5](https://img.qammunity.org/2022/formulas/mathematics/college/y2f5mxciqr3a1sc3gau0sm85167r1c9v8l.png)
so we know that a radius of 3 is right
