Question

if tan teta=3/4,find the value of sec teta and cos teta

Answer 1

Answer:

cos theta = 4/5 and sec theta=5/4

Step-by-step explanation:

Given: tan theta  = 3/4

tan^2 theta = 9/16

sec^2 theta -1 = 9/16        (we know sec^2 theta = tan^2 theta + 1)

sec^2 theta = 1+9/16

                    = 25/16

sec theta = 5/4

cos theta = 1/sec theta

cos theta = 4/5

Answers cos theta = 4/5 and sec theta = 5/4
