Question 5
(a)
If 13 sin A = 12
find sec A-tan A.​

Answer 1

Answer:

0.2

Step-by-step explanation:

Given,

13 sin A= 12

=> sin A = 12/13

let,

Perpendicular = 12x

hypotenuse = 13x

therefore, base = $\sqrt{ {(13x)}^{2} - {(12x)}^{2} }$

= 5x

=> sec A = 13/5 and, tan A = 12/5

now the question is,

sec A - tan A

=> 13/5 -12/5

=> 1/5 = 0.2
