Answer:
3x - 9
Step-by-step explanation:
We already have the expression 4x + 2x − 3x − 9. Now, we just have to add like-terms. This will give us 3x - 9.

Using the angle addition theorem, the measure of angle 2 in the given diagram is: m∠2 = 35°
<h3>What is the Angle Addition Theorem?</h3>
Based on the angle addition theorem, the sum of two smaller angles that make up a bigger angle equals the sum of the bigger angle.
Given the following:
m∠EBC = m∠EBD + m∠2 [angle addition theorem]
Substitute
55 = 20 + m∠2
m∠2 = 55 - 20
m∠2 = 35°
