Ab is tangent to \odot ⊙ o at a (not drawn to scale). find the length of the radius r, to the nearest tenth.

r = 15.2

Step-by-step explanation:

Where AB meets the circle creates a right angle.  This is a right triangle problem involving missing sides.  This means that we will use Pythagorean's theorem to find the length of the radius.  Pythagorean's theorem applies this way:

Foiling the right side gives us the equation:

When we combine like terms, we find the squared terms cancel each other out, leaving us with

100 = 6r + 9 and

91 = 6r so

r = 15.2

yes the total will be same because in both of them the expression.is rearranged but their sign remains the same hence it hss just been shuffled
