Explanation:
Velocity of the ship is given as
the direction of the velocity of the ship is making an angle of 11 degree with the current
so we will have two components of the velocity
1) along the direction of the current
2) perpendicular to the direction of the current
so here we know that the component of the ship velocity along the direction of the current is given as
The difference between the measures of the intercepted arcs of the given circle is 45°.
A circle is defined as the set of points in a plane equidistant to each, such that it forms a closed two-dimensional figure, which is known as a circle.
- A line intersecting a circle at a minimum of two distinct points is known as a secant and the line touching the circle at only one point, is known as the tangent of a circle.
- The intercepted arc is the section of the circumference of a circle such that it is either encased by two chords or a line segment, meeting at a single point.
We are given that the angle subtended by secant and tangent, outside the circle is,
And angle measured inside the circle is,
So, the difference between the measures of the intercepted arcs is,
Thus, we can conclude that the difference between the measures of the intercepted arcs of the given circle is 45°.
