Question:

If Tan 30 is 3/4 Find the value of sin 30 + cos 30- cot 30

Tamal B.

Answer:

We Know Tan = PERPENDICULAR / BASE ... Hence - P/B = 3/4 Also from Pythagorus theorem, H^2 = P^2 + B^2 Therefore, H = 5...Hence, Sin30 = 3/5 Cos30 =4/5 and Cot 30 = 4/3. Putting the value, 3/5 + 4/5 - 4/3 = 7/5 - 4/3 = 1 / 15
