Question
In a right angle triangle, the product of two sides is
half of the square of the third side (i.e., hypotenuse). Accordingly find out the acute angle?Solution
According to the question, BCĂAB = 1/2AC2Â -----(1) BC2 + AB2 = AC2 -----(2) by Pythagoras Putting the value of AC2 in equation (2), BC2 + AB2Â = 2BC Ă AB Or BC2 + AB2Â - 2BC Ă AB = 0 Or (BC â AB)2Â = 0 Or BC â ABÂ = 0 Or BC = ABÂ Hence â BAC = â BCA = 45 (As sum of two angles other right angle in a right angle triangle is 900).
