And I saw sociallies triangle has a base angles that measure forty eight which equation can be used to find x the measure of the third angle of the isoscele's triangle and degrees

If the base angles of an isosceles triangle are each 48 degrees, we can use the equation:

x + x + 48 = 180

In this equation, x represents the measure of the third angle of the isosceles triangle.

Simplifying the equation, we have:

2x + 48 = 180

Next, we can solve for x.
