MATH 1316 North Lake College Applications of Geometry and Trigonometry Questions

 

If a central angle is very small, there is little difference in length between an arc and the inscribed chord. See the figure. Approximate the following length by finding the arc length. (Note: When a central angle intercepts an arc, the arc is said to subtend the angle.)

The ends of the railroad track in the desert are 2.5

km away from the vertex of the subtended angle. A train on the track subtends (horizontally) an angle of

5°20.

Find the approximate length of the train.

Two vertices of a triangle intersect a curve labeled arc. The side of the triangle between the two vertices is labeled inscribed chord. The equation arc length = length of inscribed chord is written above the figure.

The length of the train is about nothing

km.

(Simplify your answer. Type an integer or a decimal rounded to two decimal places as needed.)
