Secant
Step-by-step explanation:
Tangents are ongoing lines that occur on the outside of a circle.
A secant is an ongoing line that passes through a part of the circle that does not pass through the center.
A chord is a line of definite length that is entirely within the circle, stretching from one side to the other, but does not go through the center point of the circle.
Anytime you have a triangle (right triangles are preferred) where at least 2 angle measures and 1 side is known. Or, at least two sides and 1 angle measure.
OR..... 3 sides or three angles are known. So, sines or cosines could be used at almost anytime to find the sides and angles of a triangle!
The total cost of the ticket is the sum of the base ticket price, p(x) = 15x + 10, and the service charge, c(x) = 5x + 2. Therefore, from the word sum, the operation involved is Addition. This is the first among the choices given.
