Solve the equation.<br><br>5/7=10/x+2

Answer:

$x=-\frac{70}{9}$

Step-by-step explanation:

Isolate the variable by doing operations to both sides of the equation.

The work is shown below:

$\frac{5}{7} =\frac{10}{x} +2\\\\\frac{5}{7} - 2=\frac{10}{x} +2 - 2\\\\-\frac{9}{7} = \frac{10}{x}\\\\ -\frac{9}{7}*x = \frac{10}{x}*x\\\\ -\frac{9}{7}x = 10\\\\ -\frac{9}{7}x * (-\frac{7}{9})= 10 * (-\frac{7}{9}) \\\\x=-\frac{70}{9}$

Can someone help me find this arc, please.

Answer:

Arc AC = 90°

Step-by-step explanation:

Postulate:

The measure of an arc will ALWAYS be equal to the measure of the central angle of the circle.

The angle of arc AC is marked with a square.

That square mark means it is 90°.

So the arc would also measure 90°.
