Question

Find the length of the missing side.



a= cm
b= cm
c= cm

Answer 1

52 cm

Explanation:

Using pythagoras theorem

hypothenuos² = adjacent² + opposite²

• hypothenuos is the longest side
• adjacent and opposite are the two other sides

`{x}^(2) \: = \: {48}^(2) + {20}^(2) \\ {x}^(2) \: = \: 2304 + 400 \\ {x}^(2) \: = \: 2704 \\ x \: = \: √(2704) \\ x \: = \: 52cm`
