Given

Required

Determine an expression for the phase shift

Factorize the expression in bracket

The general expression is:

Where:

C/B is the phase shift

By comparing the general expression with:

Multiply both sides by -1

Hence:

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
