One exterior angle of a regular pentagon has a measure of (2x) what is the value of x
2 answers:
Answer:
x = 36° .
Step-by-step explanation:
Given : One exterior angle of a regular pentagon has a measure of (2x).
To find : what is the value of x.
Solution : We have given
One exterior angle of a regular pentagon has a = (2x).
Each exterior angle = .
Plug the values each exterior angle = 2x , number of exterior angle = 5.
2x = .
2x = 72.
On dividing both sides by 2
x = 36.
Therefore, x = 36° .

Answer:
The value of x is
Step-by-step explanation:
From the question we are told that
The length of the vertical length is
The length of the base leg is L = 330 + d units
The length of the bisecting line segment is h
The base angle is
The angle between d and line segment is
For the first angle
=>
For the whole big triangle
=>
So equating the both d
Substitute values
Answer:
Step-by-step explanation:
Let E be the set of all even positive integers in the universe Z of integers,
i.e
E = {2,4,6,8,10 ....∞}
be the characteristic function of E.
∴
For XE(2)
since x is an element of E (i.e the set of all even numbers)
For XE(-2)
since - 2 is less than 0 , and -2 is not an element of E
For { x ∈ Z: XE(x) = 1}
This can be read as:
x which is and element of Z such that X is also an element of x which is equal to 1.
∴
E = {2,4,6,8,10 ....∞}
