The measure of the angle x is 30 degree if the triangle is an equilateral triangle.
What is a circle?
It is described as a set of points, where each point is at the same distance from a fixed point (called the centre of a circle)
We have a circle in which a triangle is formed.
Here is the length of the triangle is same, means it is an equilateral triangle.
Each angle in equilateral triangle = 60 degree
The radius and the one tangent, making an angle of 90 degree
Taking bigger triangle:
Total sum of angles in triangle = 180 degree
x = 180 – 90 -60
x = 30 degree
Thus, the measure of the angle x is 30 degree if the triangle is an equilateral triangle.
