Three angles have measures that add to 180°. They have the following angle measures: m∠ABC = (x6), m∠CBD = (4x14), and m∠DBE = 5x. What is the equation to solve for 2? (1 point)
A.9x20180
B.10x+20°= 180°
C.10x20°-180°
D.x20= 180°
The equation to solve for x is:
6x + 4x + 5x = 180
Combining like terms, we get:
15x = 180
Dividing both sides by 15, we get:
x = 12
Therefore, the correct equation to solve for x is:
B.10x + 20°= 180°
