Actually Welcome to the Concept of the Equilateral Triangles.
Since, we know that, all the sides of a triangle are equal, hence it is a Equilateral triangle.
Equilateral triangle has one all angles equal to 60°.
so, major angle P = 60°
hence, 2x=60°
===> x = 30°
Answer:
Step-by-step explanation:
It's right
Given:
The function is 
.
To find:
The function 
.
Solution:
We have,
Substitute f(x)=y.
Interchange x and y.
Divide both sides by 3.
Taking power 4 on both sides.
Subtract 7 from both sides.
Substitute 
.
Therefore, the correct option is C.
