Find the length of radius r. 9.9 13 7

Mathematics
1 answer:
dem82 [27]4 years ago
4 0

Answer:

Radius = 7

Step-by-step explanation:

Since BA is tangent to circle O, it creates a 90° angle with the radius

Therefore, you can use Pythagorean theorem to solve this problem

a² + b² = c²

Let's say a is the radius

b is 5

c is 8.6

a² + 5² = 8.6²

a² + 25 = 73.96

Subtract 25 from both sides

a² = 48.96

Root both sides

a ≈ 6.997142274

What is the answer? Really confused on how to figure this out
Natasha2012 [34]

Answer:

C.\frac{2(x+2)}{(x-3)}

Step-by-step explanation:

\frac{x^2+5x+6}{x-6} \div \frac{x^2-9}{2x-12} \\\\Now,\\Before\ touching\ the\ expression,\ lets\ look\ at\ the\ indiviual\ terms\ and\ try\ to factorize\ them.\\x^2+5x+6\\=(x^2+3x+2x+6)\\=x(x+3)+2(x+3)\\=(x+2)(x+3)\\\\x-6=(x-6)\\\\x^2-9\\=(x)^2-(3)^2\\=(x-3)(x+3)\\\\2x-12\\=2(x-6)\\\\Hence,\\\frac{x^2+5x+6}{x-6} \div \frac{x^2-9}{2x-12}\\=\frac{(x+3)(x+2)}{x-6} \div \frac{(x-3)(x+3)}{2(x-6)}\\By\ flipping\ the\ second\ term\ to\ its\ reciprocal, we\ get:\\\frac{(x+3)(x+2)}{x-6} * \frac{2(x-6)}{(x-3)(x+3)}\\\\=(x+2)*\frac{2}{(x-3)}  \\=\frac{2(x+2)}{(x-3)}
