Ggiven a variable magnetic field b(r, t) = ηt4/s3ˆz [in cylindrical coordinates (s, φ, z)] where η is a constant, use ∇ × e = −∂b/∂t and ∇ · e = 0 directly to find e(r, t) in regions where the electron charge density rhoe = 0. assume that e is independent of z and φ with the boundary conditions es(s =

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°

the answer is b.6
