The value of ST is 96 degrees
what is tangent?
In geometry, a tangent is the line drawn from an external point and passes through a point on the curve. One real-life example of a tangent is when you ride a bicycle, every point on the circumference of the wheel makes a tangent with the road.
The tangent has two important properties:
- A tangent touches a curve at only one point.
- A tangent is a line that never enters the circle’s interior.
- The tangent touches the circle’s radius at the point of tangency at a right angle.
- The tangent at any point of a circle is perpendicular to the radius through the point of contact.
As, The angle measure is half the measure of the arc it intercepts.
So, <STU = 48 degrees,
then the arc = 48 * 2
= 96 degrees.
