WebStep 1: Calculation of the value of the base of a triangle. To calculate sin θ we use the formula. 𝛉 𝛉 sin ( θ) = Perpendicular ( P) Hypotenuse ( H) So, from the given we have P = - 24 and H = 25. Now, apply the Pythagoras theorem to determine the value of base B that is given by, H 2 = P 2 + B 2. Then, the value of the base will be. WebIf sinA=(3/5) and A is in first quadrant, then the values of sin2A, cos2A and tan2A are (A) 24/25, 7/25, 24/7 (B) 1/25, 7/25, 1/7 (C) 24/25, 1/25, 24/ ...
