2/5=4/10 so 9/10-4/10=5/10 which is the same as 1/2
We know that ∠ABC and ∠CBD are a linear pair. A linear pair includes angles that are formed when two lines intersect.
Linear Pair Theorm states that any 2 angles forming a linear pair are supplementary, i.e. their sum is equal to 180 degree
We also know that m∠ABC = m∠CBD = (3x-3)°
⇒ m∠ABC + m∠CBD = 180°
⇒ (3x-3)° + (3x-3)° = 180°
⇒ (6x-6)° = 180°
⇒ x = 31°
So in the above we have used A and B definition / theorem to determine the answer
First, to make both triangles congruent, we should have that angle P equals angle L, so we have the following:

Solving for x we get:
