Center of Earth
7. A scientist studies two islands shown at the right. The distance
from the center of the Earth to the equator is about 3960 mi.
a. What is the measure in radians of the central angle that intercepts tl
arc along the equator between the islands? (5pnts)
equator
b. About how far apart are the two islands? (5pnts)

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11

in geometry, parallel lines are lines in a plane which do not meet; that is, two lines in a plane that do not intersect or touch each other at any point are said to be parallel. by extension, a line and a plane, or two planes, in three-dimensional euclidean space that do not share a point are said to be parallel.

i am so sorry , i have no idea but i want points so i won't be a beginner anymore
