Area of triangle equals to 1/2*base*height.
area =129. 5
height=14. 8
other side=x
substitute in the above equation
129.5=1/2*14. 8*x
x=17.5
we got one side
now we have two sides i.e height=14.8 $ base=17.5
Now use the pythogores theorm
hypoteneouse^2=base^2*height^2
Subtitute the value
and And you will get hypoteneois which will be othwr side..
Hopes it right.... If its wrong plz forgive me...
