Step-by-step explanation:
The base of the pyramid is square shaped with given edge and altitude:
So, the pyramid is a Right square pyramid.
Height of the pyramid(h)=
Edge of the base(a)=
Volume of a right square pyramid(V)=
Putting the given values in the formula:
Volume=
volume of pyramid=
The volume of the square based pyramid is
Answer:
Step-by-step explanation:
The tangent to the angle makes an angle of 90° with the radius.
The interior angle of the equilateral triangle is 60, so that leaves 90-60 = 30° for the remaining angle with the tangent.
By the exterior angle theorem, 30°+x° = 60° (interior angle of the equilateral triangle), therefore
x = 60-30 = 30°.
For your first question: find a common denominator first
for your second question :whats 360 divided by 30??
45/900=110/x
x=(110/45)*900=2200 students
Cristine will find 2200 students when she gets to high school.
