What did this person do wrong? Honestly really stuck and do not remember geometry!

Mathematics
1 answer:
dmitriy555 [2]4 years ago
4 0

Answer:

See below.

Step-by-step explanation:

Using the right triangle altitude theorem, the correct proportions are:

\dfrac{AB}{AC} = \dfrac{AC}{AD}

\dfrac{AB}{x} = \dfrac{x}{AD}

\dfrac{25}{x} = \dfrac{x}{16}

x^2 = 25 \times 16

x = 20

AC = 20 cm

\dfrac{AB}{CB} = \dfrac{CB}{DB}

\dfrac{AB}{y} = \dfrac{y}{DB}

\dfrac{25}{y} = \dfrac{y}{9}

y^2 = 25 \times 9

y = 15

CB = 15 cm

Can anybody help me with this one?
Murrr4er [49]

Answer:

  12 cm

Step-by-step explanation:

The rule regarding secants and/or tangents is that the product of distances from their common point to the two intersection points with the circle is the same.

For the tangent the "two" intersection points with the circle are the same point, so ...

  product of tangent lengths = product of secant lengths

  (8 cm)(8 cm) = (4 cm)(4 cm +x)

Dividing by 4 cm gives ...

  16 cm = 4 cm + x

  12 cm = x

The rquation of a citcle is x^2+y^2=16 what is the radius of the circle
nadezda [96]
The radius is 4 because the original equation is x^2+y^2=r^2. So the sqrt of 16 is 4.
