The correct equations are:
m∠2 + m∠3 + m∠5 = 180°
m∠2 + m∠5 = m∠4
m∠5 + m∠6 = 180°
m∠2 + m∠3 = m∠6
Equation
Equation is an expression used to show the relationship between two or more numbers and variables.
From the diagram:
m∠2 + m∠3 + m∠5 = 180° (sum of angles in a triangle)
But:
m∠3 + m∠4 = 180° (angle in a straight line)
m∠2 + m∠3 + m∠5 = m∠3 + m∠4
m∠2 + m∠5 = m∠4
Also:
m∠5 + m∠6 = 180° (angle in a straight line)
But:
m∠2 + m∠3 + m∠5 = 180
m∠2 + m∠3 + m∠5 = m∠5 + m∠6
m∠2 + m∠3 = m∠6
