Question

Find the length of AB. There's a file attached, please I need help

Answer 1

10 cm

Explanation:

Since this is a graph sheet each box is 90°

Now in this case AB is the hypotenuse

We can solve for AB using the pythogorean theorem,

Base = 6 units

Height = 8 units

Hypotenuse =?

Then,

`{8}^(2) + {6}^(2) = {x}^(2) \\ 64 + 36 = {x}^(2) \\ 100 = {x}^(2) \\ x = √(100) \\ x = 10`
