Answer:
c = 13
Step-by-step explanation:
To find the value of c, we are to make use of Pythagoras’ theorem
From the theorem, the square of the hypotenuse equals the sum of the squares of the two other sides
Using the sides given;
c^2 = a^2 + b^2
c^2 = 12^2 + 5^2
c^2 = 144 + 25
c^2 = 169
c = √169
c = 13
