Answer:
A. 125°
Explanation:
Based on the angles of intersecting chord theorem, we have:
90° = ½(measure of arc NM + measure of arc JK)
Arc NM = 55°
Arc JK = ??
Plug in the value into the equation.
90° = ½(55 + JK)
Multiply both sides by 2
2*90 = 55 + JK
180 = 55 + JK
Subtract 55 from each side
180 - 55 = JK
125° = JK
JK = 125°
Answer:
During the northern hemisphere winter solstice, the Sun's incoming rays are perpendicular to the Tropic of Capricorn at 23.5 degrees south latitude. The Sun's path is the lowest above the horizon in locations north of the equator, and these regions experience the shortest day of the year.
