And I saosiel's triangle has the base angles that measure 55. Which witchy equation can be used to find x measure of the third angle of the isoscelosy's trying go in degrees

To find the measure of the third angle in an isosceles triangle with base angles measuring 55 degrees, you can use the equation:

Third Angle = 180 - (2 * Base Angle)

Substituting the given value of base angle as 55 degrees:

Third Angle = 180 - (2 * 55)
= 180 - 110
= 70 degrees

Therefore, the measure of the third angle in the isosceles triangle is 70 degrees.
