Answer:
Because time varies with change in longitudes
the world's current population is 7.3 billion and the world population in 1915 was 1.8 billion. The increase over the past century is 7.3 billion - 1.8 billion = 5.5 billion. So, the correct answer would be "more than 5 billion" (option D).
Answer:
D
Explanation:
If the diagonals bisect each other, that means BE=EC and AE=ED. We know that angle AEB= angle CED because they are vertical angles. We also know that angle ABE and angle DCE are congruent because the shape is a square so its opposite sides are parallel. If two parrallel sides are cut by a transveral,the transversal being segment BC then alternate interior angles are congruent. Therefore DCE and ABE are congruent. We have an angle (the vertical angle) the side (diagonals bisect each other) and we have another angle (alternate interior angles)
