A theorem in geometry states that the measure of an inscribed angle is half the measure of its intercepted arc. In the figure, ZC intercepts arc AB and AB is the diameter of the circle
Which equation is a step in showing that mZ0 90"?

10.4 inches

step-by-step explanation:

2x2x2.6

1 1/7 hope i

step-by-step explanation:

8/7 = (1 * 7 + 1) / 7 = 1 + 1/7 = 1 1/7

4+4+2x

or

2x+8

step-by-step explanation:

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.
