Answer:
AC = 
Step-by-step explanation:
Assuming you require AC
Using Pythagoras' identity in the right triangle
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides , that is
AC² + BC²= AB²
AC² + 7² = 8²
AC² + 49 = 64 ( subtract 49 from both sides )
AC² = 15 ( take square root of both sides )
AC =
≈ 3.87 ( to 2 dec. places )
Answer:
15.5
Step-by-step explanation:
So the formula here is the square of the tangent length is equal to the product of the exterior part of the secant line and total length of the secant.
So that means we have x^2=10(14+10).
After simplifying the right hand side we have the equation is x^2=10(24) or x^2=240.
To get rid of the square on the x, we square root both sides.
x=sqrt(240)
x=15.49193338
To the nearest tenths, the answer is x=15.5
So 15.5 inches is the length of x.

Since point M is the midpoint of AB, then AM=MB.
Consider the area of the triangles ABC and BMC:
where
is the height drawn from the vertex C to the side AB.
So, 
Now

Also

Now consider the area of the triangles AMD and CMD. Let
be the height drawn from the point M to the side AC.

Therefore,
