Question

From the following figuge find value of sec c ​

Answer 1

Answer:

$\frac{3 \sqrt{2} }{4}$

Step-by-step explanation:

The 3rd side of the right side triangle is $\sqrt{ {12}^{2} - {4}^{2} }$

= $\sqrt{144 - 16}$

= $\sqrt{128}$

= 8√2

sec C = $\frac{12}{8 \sqrt{2} }$

= $\frac{3}{2 \sqrt{2} }$

= $\frac{3 \sqrt{2} }{4}$
