Answer:
Larger angle= 110°, Smaller angle= 70°
Step-by-step explanation:
Let the larger angle be x and Smaller Angle be y
According to 1st Condition,
x+y=180°...(1)
According to 2nd Condition,
x-40=3y
thus, x-3y=40°...(2)
Adding Equation (1) and (2),
x gets cancelled
-2y=220°
y=110°
Substituting y=110° in eqn (1)
x+110=180
x=180-110
x=70°
