Isosceles triangle that measure 48 which equation can find the x

To find the value of x in an isosceles triangle with a measurement of 48, the equation that can be used is:

2x + 48 = 180

This equation is derived from the fact that the sum of the interior angles of a triangle is always 180 degrees, and in an isosceles triangle, the base angles are equal. So, if x represents one of the base angles, then the other base angle would also be x. Adding the apex angle of 48 degrees to the sum of the base angles gives the total sum of the interior angles of the triangle, which is 180 degrees.
