Answer:
3
Step-by-step 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.
[tex] \sqrt{} 3 {}^{2} + 4 { }^{2} = 5 [/tex]
so we know that a radius of 3 is right
