Question

if tan theta is equals to 3/4 and theta lies in third quadrant find sin theta​

Answer 1

Answer:

sin theta is 3/5

Step-by-step explanation:

as tan theta = prependicular/base

base=4 and P=3

.

.

now by pythogorous theorem

3^2+ 4^2=H^2

so H =5

now sin theta = prependicular / hypotaneous

sin theta=3/5
