Question

plz give ans for question 1 plz​

Answer 1

QUESTION 1 :

We know Sin ω = Perpendicular / Hypotenuse

We also know  : (Perpendicular)² + (base)² = (Hypotenuse)²

According to the question , perpendicular = a² - b² and hypotenuse = a²+b² .

Therefore base  = √(H+P)(H-P)

B = √(2a²)(2b²)

B =2ab

I think now you will be able to find out the other trignometric ratios .

QUESTION 2 :

HINT : Do the same thing we did here but also remember sin(90 - a) = cos(a)

Hope This Helps (✿◠‿◠)
