Question

Find the value of sin 2 awhen tan a =
2/7​

Answer 1

Answer:

Sin theta is given by = Perpendicular/

Hypotenuse

And, Tan theta = Perpendicular / Base = 2/7

{given}

Thus solving it with Pythagoras theorem we get ;

(Hypotenuse)^2 = (Perpendicular)^2 +

(Base)^2

AB^2 = [ (2)^2 + (7)^2 ] = √53 units

Sin 2A = 2/√53

Hope it helps : )
