Three angles have measures that add to 180° . They have the following angle measures: m∠ABC=(x−6)° , m∠CBD=(4x−14)° , and m∠DBE=5x° . What is the equation to solve for x ?(1 point)
Responses
10x°+20°=180°
10 x plus 20 equals 180
x°−20°=180°
x minus 20 equals 180
10x°−20°=180°
10 x minus 20 equals 180
9x°−20°=180°
