Take space straight x comma straight y comma straight z space common space from space straight R subscript 1 comma straight R subscript 2 space and space straight R subscript 3 space respectively.
straight R subscript 2 rightwards arrow straight R subscript 2 space minus space straight R subscript 1 space and space straight R subscript 3 rightwards arrow straight R subscript 3 space minus space straight R subscript 1 Taking space straight y minus straight x space and space straight z minus straight x space from space straight R subscript 2 space end subscript and space straight R subscript 3 space respectively space and space expandto space get space the space value. end style
