Answer:
36
Step-by-step explanation:
Hey There!
So if you didn't know all of the angles in a triangle add up to equal 180
so to find the missing angle we subtract the given angles from 180
180-90-54=36
therefore the missing angles is 36
Answer:
A, D , and E
Step-by-step explanation:
We have that:
is the image of CD after a dilation of scale factor n.
We use the relation between the image length and object length:
Option A
If n=3/2, then
This is true.
Option B
If n=4, then
This is false.
Option C
If n=8, then
This too is false.
Option D
If n=2, then
This is true
Option E
If n=3/4, then
This is also true.
Assuming that Anita needs hollow right circular cones, we are solving for its lateral surface area, which is given by the formula πr√(h²+r²), where r is the radius and h is the height.
r = 6 ft / 2 = 3 ft
Solving for the lateral surface area of one cone:
LSA = (3.14) (3) [√(12²+3²)] = 116.52 sq ft.
Since she needs 10 cones:
10 * 116.52 sq. ft = 1,165.2 sq ft.
She will need 1,165.2 sq ft of material.
