let�s the largest angle be , the larger , and the smallest angle
the sum is: ...............eq.1
if the larger is � greater than the smallest, we have
....eq.2
if the largest is twice the smallest angle, we have
...............eq.3
go to
...............eq.1, substitute and from eq.1 and eq.3
....solve for

�
go to ....eq.2, plug in

�
go to ...............eq.3, plug in

�
so, the largest angle of a triangle is �

Find the largest angle of a triangle where the larger is 20� greater than the smallest and the largest is twice the smallest angle.

Let larger be L
Then smallest =
Also, larger (middle) =
We then get:
