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)
10x°+20°=180°
x°−20°=180°
9x°−20°=180°
10x°−20°=180°
The correct equation to solve for x is:
m∠ABC + m∠CBD + m∠DBE = 180°
(x-6)° + (4x-14)° + 5x° = 180°
Combining like terms:
10x-20 = 180
10x = 200
Dividing both sides by 10:
x = 20
So, the correct equation to solve for x is:
10x - 20 = 180°
