Answer: It is not possible that two triangles that are similar and not congruent in spherical geometry.
Step-by-step explanation:
For instance, taking a circle on the sphere whose diameter is equal to the diameter of the sphere and inside is an equilateral triangle, because the sphere is perfect, if we draw a circle (longitudinal or latitudinal lines) to form a circle encompassing an equally shaped triangle at different points of the sphere will definately yield equal size.
in other words, triangles formed in a sphere must be congruent and also similar meaning having the same shape and must definately have the same size.
Therefore, it is not possible for two triangles in a sphere that are similar but not congruent.
Two triangles in sphere that are similar must be congruent.
Answer:
82.72m
Step-by-step explanation:
Volume = πr2h
= 3.142*7*7*14
= 2,155.41m³
Now that we hav the volume of earth, we go on to find the raduis of the spread
2155.41m³ = 3.142*r²*0.4
2155.41m³ = 1.26r²
r² = 1,710.64
r = 41.36m
Width = diameter = 2r = 82.72m
<u>Answer:</u>
24
<u>Step-by-step explanation:</u>
To find ƒ(6), we have to substitute x = 6 into the expression for ƒ(x):
ƒ(6) = (6)² - 2(6)
= 36 - 12
= 24
4 divided by 1/4
4 times 4/1
4 times 4 equals 16
