Question

Find the length of the the missing triangle side

Answer 1

B. 5

Explanation:

Formula: a^2 + b^2 = c^2

Solution: a is the missing side or x

b is 12 cm

c is 13 cm

x^2 + 12^2 = 13^2

x^2 + 144 = 169

• You need to transpose 144 to the right side so that it will become :

x^2 = 169 - 144

x^2 = 25

• Now you have to discard the square root by using the square root property, it will become:

x = 5

Now the final answer is x = 5

Answer 2

So the right answer is 5.
