<PRE><B>Question 261660</B>
One angle of a triangle is three times the measure of second angle. The third angle measures 12 less than twice teh second angle. find the measures of the angles. MUST SHOW WORK!

Let the angle be 3x
The second angle is x
The third angle is 180-4x   		sum of all angles of triangle  = 180

180-4x  =2x-12
6x = 180-12
6x=168
X=28
The other angle is 84
The third angle = 68
