Assuming that the center of each circle is at point C and D, then both have a radius of 7cm. We know that the formula for solving area of the circle is A=pi*r².
Then we solve area of once circle multiplied by two to get the total area of the given circles. The solution is shown below:
C1 area=3.1416*7²
C1 area=153.9384 cm²
Summation of the area of circle C and D is shown below:
Sum area=2*153.9384
Sum area=307.8768cm²

The answer is 98pi.

Using the law of sines, find the solutions for the missing inputs.

SashulF [63]

$\frac{a}{ \sin(a) } = \frac{b}{ \sin(b) }$
$\frac{12}{ \sin(38) } = \frac{b}{ \sin(85) }$
$\frac{12}{ \sin(38) } = \frac{a}{ \sin(57) }$
$180 - (85 + 38) = 57$
$\frac{12}{ \sin(38) } = \frac{b}{ \sin(85) }$
$\sin(85) \times \frac{12}{ \sin(38) } = b$
$\sin(57) \times \frac{12}{ \sin(38) } = a$
sorry for the order of steps

Can someone help me with my geometry homework

Usimov [2.4K]

Answer:

x=13

Step-by-step explanation:

I guess the angles are supplementary,Which means they have a sum of 180°.

11x - 15+5x-13=180

16x-28=180

16x=208

x=13

Explanation:

If there are 7 options (7 tiles) but only 2 possibilities (2 tiles with the number one), our probability could be expressed as:

2/7 or 29% approximately for the first tile.
