Final answer:
The direct expression for mPcb is given as mPcb = 43x + 1. Without additional context or a diagram, we cannot establish relationships between the angles to solve for x, therefore we use the expression given for mPcb as the answer (Option B).
Step-by-step explanation:
We are given three expressions involving angles:
- mPcb = 43x + 1
- m2DCB = 165x – 1
- mZDCP = 120°
From the problem, it looks like we're dealing with angles in a geometric figure, possibly a polygon or intersecting lines. Unfortunately, without additional context or a diagram, we cannot establish the relationships between these angles (whether they are supplementary, complementary, or otherwise related). However, we are given explicit expressions for mPcb and m2DCB, but no equation or context to solve for x.
With the information provided, without assuming any relationship between these angles due to lack of context, the answer to 'Find mPcb' which is directly given in the question is mPcb = 43x + 1 (Option B).
