begin mathsize 16px style To space find space length space of space altitude space from space the space vertex space straight B. Find space equation space of space AC. Slope space of space AC equals fraction numerator 5 minus left parenthesis negative 4 right parenthesis over denominator negative 1 minus 2 end fraction equals fraction numerator 9 over denominator negative 3 end fraction equals negative 3 Let space BD perpendicular AC. Slope space of space BD equals fraction numerator negative 1 over denominator negative 3 end fraction equals 1 third Equation space of space BD space with space slope space 1 third space and space point space left parenthesis 3 comma 3 right parenthesis straight y minus 3 equals 1 third open parentheses straight x minus 3 close parentheses 3 straight y minus 9 equals straight x minus 3 straight x minus 3 straight y plus 6 equals 0 Now space you space can space find space perpendicular space distance space of space the space vertex space straight B thin space left parenthesis 3 comma 3 right parenthesis space to space the space line space AC. space left parenthesis find space equation space of space AC right parenthesis end style
