The diagram of the scenario is shown in the attached photo.
The shadows of Eden and Jane formed two right angle triangles ABC and DBE. Also, triangle ABC and BDE are similar triangles. Therefore
DE/AC = DB/AB = BE/BC
Let DE be x feet
AC = 5 1/3 = 16/3 feet
BE = 8.5 = 17/2 feet
BC = 8 feet
Therefore
x/(16/3) = (17/2)/8
3x/16 = 17/16
Cross multiplying
3x = 17
x = 17/3
x = 5 2/3
Answer:
A) Measure of an interior angle of polygon = 150°
B) No of sides = 12
C) Sum of all interior angles = 1800°
Step-by-step explanation:
Measure of interior angle of polygon = 180°- measure of exterior angle of polygon
= 180°-30°
= 150°
B.
