Sin=7/25& cos=24/25

Govind B 1 year, 2 months ago

Ans. Given : in triangle ABC , right angle at B , AB=24cm and BC=7cm To find: sinA and cos A Now by Pythagoras AC² =AB²+BC² AC² =(24)²+(7)² AC = √576+49 AC =√625 AC =√(25)² AC =25cm We have AC =25 Now SinA=perpendicular/ hypothesis SinA = BC/AC therefore, SinA= 7/25 Now Similarly, CosA =base/ hypothesis CosA = AB/AC CosA = 24/25 Hence, sinA =7/25 CosA =24/25

First thing. You should complete the NCERT book. First priority must be your NCERT book. Then you can check previous year sample papers. Then you have to go for extra and then try to solve the Questions. If you found you lose the confidence then see the answers this makes more better
