<u>Given</u>:
The measure of angle EFG is 
The measure of arc GE is 
We need to determine the value of x.
<u>Value of x:</u>
The value of x can be determined using the inscribed angle theorem.
Thus, we have;

Substituting the values, we have,




Hence, the value of x is 8.
Therefore, Option B is the correct answer.
Answer:b=5
Step-by-step explanation:the formular for pythagoras theory is
C^2=a^2+b^2
13^2=12^2+b^2
169=144+b^2
Collect like terms
169-144=b^2
b^2=25
Take the the square root of both sides
b=square root of 25
b=5
