Add
to both sides:

Add the fractions in the left hand side:

So, the equation becomes

Multiply both sides by 10:

Divide both sides by 9:

Answer:
Step-by-step explanation:
m∠5 +m∠6 = 180° ( the angles form a line)
m∠2 + m∠3 = m∠6 ( exterior angle is the sum of 2 not adjacent angles)
m∠2+m∠3+m∠5= 180° (sum of angles in a triangle is 180°)
