Can you help me with this (The drawing will be provided. HINT. Use the difference of squares formula a- = (a - b)(a + b). Let AABC be a right-angled triangle with the right angle in A and base BC 50 •6 meters. Let AD be the beight correspond- ing to BC. II AB 30 •6 meters and BD= 18•6 meters, find: AC , DC, AD)
