Question 870303
In a triangle,the largest angle is 20 degrees larger than the smallest angle.Write down the three angles it could be?'
---------
Call them A, B & C
A = B + 20
A + B + C = 180
C = 180 - (A + B)
C = 180 - (2B + 20)
C = 160 - 2B
---------
B < C < A since A is the largest and B is the smallest
B < 160 - 2B
3B < 160
B < 160/3 degs
--> A < 220/3 degs
A + B < 380/3
