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
196 + x = 500
Subtract 196 from both sides:
196 on the left is cancelled out, and you’re left with x = 304
