The value of x is 
Explanation:
The given expression is 
We need to find the value of x.
To determine the value of x, let us solve the expression for x.
Multiplying the term 3 within the bracket, we have,

Simplifying, we get,

Adding both sides of the expression by 13x, we have,

Adding both sides of the expression by 18, we get,

Dividing both sides of the equation by 21, we get,

Thus, the value of x is

Answer:
Answer is yes
Step-by-step explanation:
Given in the picture are two circles which are congruent.
This suggests that the radii of the two circles are equal.
Also the central angle of the two circles are congruent (given)
Consider triangles ABC and XYZ,
AC =XY: AB = YZ:
Angle A = Angle X
By SAS theorem, the two triangles are congruent.
Hence BC = YZ
So yes is answer.
