An isosceles triangle has base angles that measure 42 degrees each. Write an equation that can be used to find z, the measure of the third angle.

You move the constant to the right side and change its sign to be 9z= -6 -8. that’s the first step.the second step would be calculate the difference of -8-6 to get -14. you equation should now be 9z=-14the last step is to divide both sides by 9 to get z=-14/9hope this
