Given :
An isosceles triangle has two angles that measure 37° each.
Let the measure of the third angle = x
The sum of the angles of the triangle = 180
so, the first equation of the third angle will be
[tex]x+37+37=180[/tex]The second equation that can be used to find the third angle is :
[tex]180-x=2\cdot37[/tex]The solution for the equation will be the same
[tex]x=106[/tex]
