<u>Answer is 10 </u>
Step-by-step explanation:
I hope this is correct!
Explanation:
Remember: we have to isolate the variable x, so that means we have to get x by itself.
Step 1:
Let’s look at our equation:

Let’s subtract 2x from both sides of the equation, since our goal is to isolate the variable. You could also subtract 6x from both sides, but you would end up with a negative number, and I find it easier to deal with positive numbers.

Step 2:
Now, let’s subtract 57 from both sides of our equation.

Step 3:
Since we have to isolate x, let’s divide both sides of the equation by 4.

Our final answer: x = 64.5

Answer:

Step-by-step explanation:
we know that
The diameter divide a circle into two equal parts
so
The measure of arc FAC is equal to 180 degrees (Remember that a complete circle subtends a central angle of 360 degrees)
we have that
---> given problem
----> by central angle
----> given problem
so

therefore
----> by angle addition postulate
substitute
