Look at the picture.

x + 2x = 12

3x = 12 <em>divide both sides by 3</em>

x = 4

AB = 12 + x

therefore AB = 12 + 4 = 16

<h3>Answer: AB = 16.</h3>

Step-by-step explanation:

$\text{LHS}=\frac{1}{\sec \theta-\tan \theta}\\=\frac{\sec \theta+\tan \theta}{(\sec \theta-\tan \theta)(\sec \theta+\tan \theta)}\\=\frac{\sec \theta+\tan \theta}{\sec^{2} \theta-\tan^{2} \theta}\\=\frac{\sec \theta+\tan \theta}{1}\\=\sec \theta+\tan \theta\\=\text{RHS}$
