There are at least two equal angles in an isosceles triangle.
A%2BA%2BB=180
and
A=35%2BB
Substituting,
%2835%2BB%29%2B%2835%2BB%29%2BB=180
70%2B3B=180
3B=110
B=110%2F3
and
A=105%2F3%2B110%2F3
A=215%2F3
Or if
B=35%2BA
Then,
A%2BA%2B35%2BA=180
3A=145
A=145%2F3
and
B=105%2F3%2B145%2F3
B=250%2F3
.

Without knowing at least one side, you cannot calculate perimeter or area of either triangle.
