On the circle below, tangent line BC¯¯¯¯¯ is constructed by striking an arc from point D that intersects circle A at point B. Th
weqwewe [10]

Answer:

\huge\boxed{BD = 12\ units}

Step-by-step explanation:

If AB = 5 , then AE = 5 [Radii of the same circle]

So,

AC = AE + EC

AC = 8+5

AC = 13 units

Now, Using Pythagorean theorem to find the missing side i.e. BD because tangent strikes the circle at 90 degrees making the triangle a right angled triangle

c^2=a^2+b^2

Where c = AC , a = BD and b = AB

13^2 = BD^2+5^2

169 = BD² + 25

Subtracting 25 to both sides

169 - 25 = BD²

BD² = 144

Taking square root on both sides

BD = 12 units

Katyanochek1 [597]

Answer:

C

Step-by-step explanation:

Using the cosine ratio in the right triangle

cosθ = \frac{adjacent}{hypotenuse} = \frac{7}{16} , then

θ = cos^{-1} (\frac{7}{16} ) ≈ 64° ( to the nearest degree )
