Question

Find the secant of both angle A and angle B.

A. sec A = 13/5; sec B = 13/12
B. sec A = 13/12; sec B = 13/5
C. sec A = 12/13; sec B = 5/13
D. sec A = 24/10; sec B = 10/24

Answer 1

The secant of an angle is the ratio of the hypotenuse to the shorter side adjacent to an acute angle. It is the reciprocal of cosine function. Therefore, the correct answer from the choices is option B.

sec A = 26/24 =13/12
sec B = 26/10 = 13/5
