which term describes an if statement inside of another if statementthree angles have measures that add to 180°. they have the following angle measures: m abc = (×-6)°, m cbd = (4×-14)°, and m dbe = 5x°. what is the equation to solve for x?

A. 10x° + 20° =180°
B. X° + 20° = 180°
C. 10x° - 20°= 180°
D. 9x° - 20° = 180°

The equation to solve for x is: 10x° - 20° = 180°

So the correct option is C. 10x° - 20° = 180°
