The angle A in the above triangle is actually very close to 33.7 degree

ok, so if arcsin(x) means the inverse of sin(x)  (not like 1/sin(x)) so if sin(A)=b then arcsin(b)=A we are given sin(A)=0.422618 so therfor arcsin(0.422618)=A we use our calculator and get A=436332024  radians or about 25 degrees so, if we assume the missing angle is 90 then all angles add to 180 so 90+A+B=180 A+B=90 25+B=90 B=65 A=25° B=65°
