BC is tangent to circle O, and since radius OB is perpendicular to this tangent, then the triangle must have a right angles in it, making it a right triangle.

The triangle could also be scalene, but that is not for sure, meaning it is primarily a right triangle.

What does that equal

son4ous [18]

Answer:

$3-\sqrt{10}$

Step-by-step explanation:

We are given an expression and are asked to find what it equals. We can see that the two square roots are being multiplied, therefore they follow the same standard as any multiplication problem, do as followed :

$\sqrt{5} *\sqrt{2}$

$\sqrt{10}$

Since a square root and constant number are different terms, we cannot combine them together, therefore leave as is :

$3-\sqrt{10}$
