Explanation Given: From the given right angled triangle, the measure of the sides a and b are observed to be ( 12 3 8 ) " and ( 16 5 16 ) " , respectively. The angle C is 90 degree. Theorem used: Pythagorean theorem: If the side c is the hypotenuse, and sides a and b are the legs of a right angled tringle, then c 2 = a 2 + b 2 . Calculation: Obtain the measure of the side c as follows. Substitute a = 12 3 8 and b = 16 5 16 in c 2 = a 2 + b 2 . c 2 = ( 12 3 8 ) 2 + ( 16 5 16 ) 2 c = ( 99 8 ) 2 + ( 261 16 ) 2 = 153.141 + 266.098 = 419.239 ≈ 20.5 Thus, the measure of the side c is 20.5 in _ . Obtain measure of the angle A as follows. Substitute adjecent side = 16 5 16 and opposite side = 12 3 8 in tan A = opposite side adjecent side
