15 inches
Explanation:
James needs to use the Pythagoras theorem, which states that in a right-angle triangle, the sum of the squares of the other two sides is equal to the square of the hypotenuse.
c²=a²+b²
we know that a is 9 inches and that be is 12 inches
c²= (9)²+(12)²
c²= 81+144
c²=225
c=√225
c=15
after applying the measures to the Pythagoras theorem formula,
we found out that the length of the straight-edge needs to be 15 inches
