so...................putting values

2xk/base

=2x5/base

=10/8

=1.25 Ans

since the 2 equal sides are of 5cm each so on considering half of the triangle we have the base as 4cm, hypotenuse as 5 cm and perpendicular we have to calculate so on following pythagoras theorem we have 5*5=perpendicular *perpendicular+4*4

=> 25=x*x + 16

=>25-16=x*x

=>9=x*x

=>x=√9=3cm.
