We have two similar triangles.
A ( small ) = 10.5 m²
A ( large ) = 94.5 m²
h ( small ) = ? and h ( large ) = 9 m.
A s : A l = h s² : h l ²
10.5 : 94.5 = h s² : 9²
h s² * 94.5 = 81 * 10.5
94.5 h s² = 850.5
h s² = 850.5 : 94.5
h s² = 9
h s = √ 9
h s = 3 m
Answer: The altitude of the smaller triangle is 3 m.
Answer:
C.) Earth completing a rotation on its axis
Explanation:
A great difference exist between Rotation and Revolution.
While rotation deals with the earth making a move about it axis,just like a sphere spinning around it axis and this occurs every 24 hours.
Revolution on the other hand involves the earth making a complete move around the sun and this takes 365 days with an exception of 366 days during a leap year.
