In AUVW, VW UV and mZU = 74°. Find mV.

z = 3

Explanation:

Δ UWV and Δ UWX are similar triangles , thus corresponding angles are congruent , that is

∠ UWV = ∠ UWX , substitute values

9z - 24 = z ( subtract z from both sides )

8z - 24 = 0 ( add 24 to both sides )

8z = 24 ( divide both sides by 8 )

z = 3

radiative zone

explanation    

radiative zone is the layer of the sun which energy is transferred away from the core by radiation. although, the core is the only part of the sun that produces an appreciable amount of heat through fusion. in fact, 99% of the energy produced by the sun takes place within 24% of the sun's radius.
