The apothem is the distance from which the altitudes of the triangle to one of its sides. It can be calculated through the equation below,
tan 30° = apothem / 0.5(length of side)
Substituting the known values,
tan 30° = 5 / 0.5x
The value of x from the equation above is 17.32. Multiplying this value by 3 (because a triangle has 3 sides), we get an answer of 51.96 cm or approximately equal to 52. Thus, the answer is letter B.
Answer:
33 degree
Step-by-step explanation:
Let m1 be x
m2= x+1
A/Q
--> m1+m2= 67
--> x+x+1= 67
--> 2x+1=67
--> 2x= 67-1
--> 2x=66
--> x= 66/2
--> x= 33
So, m1= 33 degree

Answer:
20
Step-by-step explanation: multiply
Equilateral triangle has all equal sides
let y be 1 side
imply 3y=perimeter
Given perimeter=8x+6
So y=1perimeter/3=(8x+6)/3=(8x/3)+2
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.
