Find the length of the missing side
The length of the missing side is

52m

Step-by-step explanation:

as this is a right angled triangle (has a 90° angle), you can use the Pythagoras theorem to work out the missing side.

Pythagoras theorem:

side A squared (labeled on diagram below)

+ side B squared

= side C squared

for this example though, we don't know the length of side B so we need to swap around the formula.

replace the letters for their numbers,

(calculate)

2704 = b² but we want b by itself so we will square root b² (2704)

∴ side B = 52m (remember we were calculating in meters)

I hope this was helpful :-)
