Which statement is true about setting up a proportion to solve for the missing measure?
1.corresponding parts must be in different positions.
2.corresponding parts must be in the same position.
3.the two ratios are not equal.
4.the enlargement is not proportional to the original figure.
consider the enlargement of the triangle.

B)

Corresponding parts must be in the same position.

Step-by-step explanation:

corresponding parts must be in the same position (B)

Step-by-step explanation:

In trigonometry, secant in a right triangle, is the reciprocal of the cosine of an angle symbol: sec while cosine is in a right triangle, is the ratio of the length of the side adjacent to an acute angle to the length of the hypotenuse.

The cosine of an angle is the ratio of the length of the side adjacent to the angle divided by the length of the hypotenuse of the triangle. The cosine of ∠A will be abbreviated as cos ∠A

The secant of x is 1 divided by the cosine of x: sec x = 1 cos x , and the cosecant of x is defined to be 1 divided by the sine of x: csc x = 1 sin x .
