heya...here's your answer..
let the triangle be ABC
one of the angles let A be 65°
A=65°
and
B-C=25°......(1)
A+B+C=180°
hence,
65+B+C=180
hence
B+C=115°....(2)
Comparing 1 and 2
2B=140
B=70..put in 2
and C=45°
hence B=70° & C=45°
hope it helps u!!

LET OTHER TWO ANGELES ARE x, x+25 therefore x+x+25+65=180{sum of interior angle of triangle is 180] x=45 therefore other angles are 45 ,70 degree
