DIA [1.3K]

Answer:

Step-by-step explanation:

Angle BCA is inscribed in that circle. The rule is that the inscribed angle is half the measure of the arc it intercepts. The arc it intercepts is arc AB which measures 96 degrees. That means that

$4x+4=\frac{1}{2}(96)$ and

4x + 4 = 48 and

4x = 44 so

x = 11

Choice A is the one you want.

Please help with this question

Alchen [17]

$T = 2\pi \sqrt{\dfrac{L}{32}}$

$\dfrac{T}{2\pi} = \sqrt{\dfrac{L}{32}}$

$L = \dfrac{32 T^2}{4\pi^2} = \dfrac{8T^2}{\pi^2}$

$L = \dfrac{32 (2.2)^2}{4(3.14)^2} =3.927 \textrm{ feet}$

Second choice: 4 feet
