Question

if tan theta = cos [30+theta ] find thevalue of theta

Answer 1

Answer:

Step-by-step explanation:

Given, tan theta= cot (30+theta)  can be written as,

             tan theta = tan(90 - (30 + theta))

            tan theta = tan(90 - 30 - theta)

            theta = tan 60 - theta

             theta + theta =  60

                theta = 60/2
