The measures of two angles in a triangle are shown in the diagram. Which equation can be used to find the value of x?
60
2( 48 ) +x = 360
2( 48 ) +x = 180
48 + 2x = 360
48 +2x = 180

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?
60
84 + z= 180
42 + z =180
42 + 2z = 180
84 + 2z = 180
