What would the angles need to be increased to ?

An isosceles triangle has two angles of 25°. The length of the side joining these two angles is 48mm. What would the angles need to be increased to in order to double the area of the triangle if the 48mm side remains unchanged

Because now there's 2 "right triangles"; the 123.6° is now "γ". You see α (alpha) is the smallest angle; β (beta) " mid " ; γ (gamma) " largest ". Side "a" opposite "α"; "b" " "β"; "c" " "γ".
