Question

How to find unknown side

Answer 1

C = 10

Explanation:

Find the last side of the triangle using the Pythagorean theorem.

`a^(2) +b^(2) =c^(2)`

You have a and b already, a = 6, b = 8

`6^(2) +8^(2) =c^(2) \\\\`

solve this to get

`64 + 36 = √(100)`

C = 10

Apply the same to the other 2 triangles. C is your longest side!
