Exercise 8.1 class 10
In triangle ABC right angled at B,
if tan A = 1/(√3) ,
find the value of:
(i) sin A cos C + cos A sin C
(ii) cos A cos C – sin A sin C
Hint💡 :
tan A = P/B
Use Pythagoras Theorem,
Find Hypotenuse
Remember📖:
sin A = P/H
cos A = B/H
Perpendicular is the side opposite to the given angle
Base is the side adjacent to the given angle
