For convenience, we choose each side to be length 2. When you bisect an angle, you get 30 degrees and the side opposite is 1/2 of 2, which gives you 1. Using that right triangle, you get exact answers for sine of 30°, and sin 60° which are 1/2 and the square root of 3 over 2 respectively. Exact values of sin(30), cos(30), tan(30), csc(30), sec(30), cot(30), Find exact values of all trigonometric functions when the angle is 30 degrees,blackpenr Question: Question 4 Solve The Problem.

Tan 30 = sin30/cos30 Sin30 = 1/2 , cos30= √3/2 So tan30 =sin30/cos30 = (1/2) ÷(√3/2) =1/√3 So Ans will be 1/√3 All the best and upvote if it's helpful
