Answer :
67.5 degrees
Let the measure of two equal angles of the triangles is x.
Thus, the angles of the triangles are x, x and 45 degrees.
The sum of the measures of the angles of all triangles is 180 degrees.
Hence, the equation is
x + x + 45 = 180
Solve the equation for x
2x + 45 = 180
2x = 180 - 45
2x = 135
x = 67.5
Therefore, measure of other two angles are 67.5 degrees.
Let x,y be two different numbers
suppose x^2=y^2
then x^2-y^2=0
which yields (x+y)(x-y)=0
so either x=y or x=-y
In any case, x and y must be the same value
also when a vairable is squared like y=x^2
we must note that there are 2 possible solutions
x=(+/-)sqrt(y)
