Question

If tan alpha = 5/12, find the value of sec alpha?​

Answer 1

Answer: sec alpha = 13/12

Step-by-step explanation:

Tan alpha = 5/12

From trig ratio [triangle]

Tan alpha = Opposite side/Adjacent side = 5/12

Hence,

Hypotenuse = Root[5^12 + 12^2] = Root[25+144] = Root169 = 13

Sec alpha = 1/cos alpha = hypotenuse/adjacent side = 13/12
