Two points on a circle determine a
minor arc and a major arc; the
is the arc with
the lesser measure.

A minor arc is the shorter arc connecting two endpoints on a circle . The measure of a minor arc is less than 180° , and equal to the measure of the arc's central angle . ... An arc measuring exactly 180° is called a semicircle .

step-by-step explanation:

11.2

step-by-step explanation:

when doing tangent the tangent of the angle is equal to the opposite side from the angle over the adjacent side to the angle.

tan43 = x / 12

move 12 over by multiplying each side by 12

12tan43 = x

x = about 11.2
