Hillary is using the figure shown below to prove the Pythagorean Theorem u sin triangle similarity: In the given triangle ABC, angle A is 90° and segment AD is perpendicular to segment BC. Which of these could be a step to prove that BC2 = AB2 + AC2?

i think it is 70

step-by-step explanation:

b. x + 1

parallelogram is the   answer

large crystals result from very slow cooling.

evaporation of water: this would produce an evaporite which is a sedimentary rock. like a salt pan in a desert. not possible to have volcanic rocks originate this way.

crystalization in molten earth: slow cooling over time. (hundreds to millions of years)

crystalization at earth's surface: this results in fast cooling. (a few hours to a few months or years)

crystalization from cooling off hot water: that would be a hydrothermal deposit. while associated with volcanics they are not volcanic rocks themselves and usually occur fairly rapidly.
