Question

The lengths of two sides of a triangle are 89 cm and 38cm.find the third side

Answer 1

hey!!!

Length of one side= 89cm
Length of second side= 38cm
Length of third side=x

So equation formed:
$x + 89 + 38 = 180(sum \: of \: angles \: of \: a \: triangle)$
$x + 127 = 180$
$x = 180 - 127$
$x = 53$
The third side of the triangle is 53cm.

First side= 89cm
Second side= 38cm
Third side= 53cm
