Answer:

B

Step-by-step explanation:

The line from the vertex to the base is a perpendicular bisector and divides the isosceles triangle into 2 right triangles with hypotenuse x

Using Pythagoras' identity in either of the 2 right triangles, then

x² = 12² + 5² = 144 + 25 = 169 ( take the square root of both sides )

x = \sqrt{169} = 13 → B

Answer:

C. 72\pi

Step-by-step explanation:

The radius of the circle is 24 units, then the area of the whole circle is

\pi r^2=\pi \cdot 24^2=576\pi \ un^2.

The shaded circle is limited by 45° angle, so its area is

\dfrac{45}{360}=\dfrac{1}{8}

of the area of the whole circle.

The area of the shaded circle is

\dfrac{1}{8}\cdot 576\pi =72\pi \ un^2.
