smaller angle=70
larger angle=110
Explanation:
Let us write this problem in terms of x and y:
- where x is the smaller angle
- and y is the larger angle
We know that the large angle (y) is equal to 30-2*the smaller angle(x)
Knowing also that the angle are supplementary,
Substituting y by its value in terms of x we get:
Adding 30 to both sides of the equation to isolate the unknown's term:
Dividing both sides of equation by 3 to isolate x:
