Answer:
16/15
Step-by-step explanation:

The two minus signs cancel, so the result is positive.
X=12. So this one says that it has 3 congruent sides so therefore it has to have 3 congruent angles. Here we have angle 2 and we have angle 60. Given the definition of triangle congruence, we can say that 60 is angle 2 and that the third angle is also 60 but it’s not relevant in this problem. So knowing that angle 2 is 4x+12 we solve for x by seeding that equal to 60 and then solving for x we get x=12. Hope this helps!!!!
Given that the radius of the circle is 6 cm.
The central angle is 120°
We need to determine the length of AB.
<u>Length of AB:</u>
The length of AB can be determined using the formula,

Substituting
and
in the above formula, we get;

Simplifying the values, we get;



Substituting π = 3.14, we have;


Thus, the arc length of AB is 12.56 cm
