given
a+b=c
& a-b=50
and we know sum of interior angles of a triangle is 180° then
a+b+c=180°
then from from a-b=50 we have a=50+ b then
put this value in a+b=c we get c=50+2b
then put values in a+b+c=180°
so 50+b+b+50+2b=180
then b=20°
then a-20=50 so a=70°
then 20+70+c=180
then c=90°
a+b=c
& a-b=50

then a-20=50 so a=70°
then 20+70+c=180
then c=90°
