Answer» tan A = 4/3We know,tan A = P/B Using pythagoras theoramH^2 = P^2 + B^2H^2 = 44 + 33H^2 = 16 + 9 = 25H = 5 Other trigonometric-functionsare:sin A = P/H = 4/5cos A = B/H = 3/5cot A = B/P = 3/4sec A = H/B = 5/3cosec A = H/P = 5/4 thanks jaan

Answer»

tan A = 4/3We know,tan A = P/B

Using pythagoras theoramH^2 = P^2 + B^2H^2 = 4*4 + 3*3H^2 = 16 + 9 = 25H = 5

Other trigonometric-functionsare:sin A = P/H = 4/5cos A = B/H = 3/5cot A = B/P = 3/4sec A = H/B = 5/3cosec A = H/P = 5/4
