    Question Image
    2( 48 ) +x = 360
    2( 48 ) +x = 180
    48 + 2x = 360
    48 +2x = 180

  • Q2
    An isosceles triangle has base angles that each measure 42°. Which equation can be used to find z, the measure of the third angle of this isosceles triangle in degrees?
    84 + z= 180
    42 + z =180
    42 + 2z = 180
    84 + 2z = 180
