In the first triangle
Third angle $$ = 180^{\circ} - (40^{\circ} + 30^{\circ}) $$
By further calculation
$$ = 180^{\circ} - 70^{\circ} $$
So we get
$$ = 110^{\circ} $$
Obtuse angle of first triangle is $$110^\circ$$
and obtuse angle of second triangle is $$100^\circ$$
first triangle not congruent to second triangle
