(1 point) For each of the indefinite integrals below, choose which of the following substitutions would be most helpful in evaluating the integral. Enter the appropriate letter (A, B, or C) in each blank. DO NOT EVALUATE THE INTEGRALS. A. x=6tanθ B. x=6sinθ C. x=6secθ

1- optionC X= 6secθ

2- option B. X= 6sin(θ)

3- option A. X= 6tan(θ)

4- option C. X= 6sec(θ)

5- option A. X= 6tan(θ)

Step-by-step explanation:

Attached is the full question

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.
