What is the movement of plates that forms ocean trenches? a. convergent b. divergent c. subduction

answer: divergent is when the tectonic plates move away from each other.

the areas in the ocean where one earth crust goes under another due to plate tectonics, is called a subduction zone, since it's the location where one crust subducts under the area, creating a large trench in the earth's surface.

the anwser is d) 75°

step-by-step explanation:

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°
