A+B+C=180°(By angle sum property of a triangle)
Given that A=B+C, we can substitute B+C by A
So,
A+A=180°
2A=180°
A=90°

angle A+ angle B +angle C = 180 degree    (angle sum property of triangle)
ang B+ang C+ ang B+ ang C = 180        (Ang A= ang B +ang C)
2 ang B+2 ang C= 180
2( ang B + ang C)= 180
ang B+ ang C = 180/2  = 90 degree
hence, ang A = 90 degree  ( ang A = ang B + Ang C)
HOPE IT HELPS!
