Question

Find the missing side in each triangle using any method.

AC has a length of ____ units. DE has a length of ____ units.

Answer 1

AC length is 13 units.

DE length is 100 units.

Using pythagoras theorem:

find side AC of triangle ABC:

`\sqrt{ {5}^(2) + {12}^(2) }`

find side DE of triangle DEF:

`\sqrt{ {26}^(2) - {10}^(2) }`
