Complete Question

Find the missing side length of a Triangle and enter your answer in the box below. If necessary, round your answer to 2 decimal places,

Side a = 5

Side b = 12

Side c = ?

Answer:

The missing side length is 13

Explanation:

From the above question, we can see that we are given two of the sides of a triangle.

We solve for side c using Pythagoras Theorem

Hence:

a² + b² = c²

5² + 12² = c²

25 + 144 = c²

169 = c²

Square root both sides

c = √169

c = 13
