Expert Solution
Step 1: Given data

The co-ordinates of the points from the given figure in vector for is as below.

Point space straight O equals 0 straight i with hat on top plus 0 straight j with hat on top plus 0 straight k with hat on top Point space straight A equals 0 straight i with hat on top plus 2.9 straight j with hat on top plus 0 straight k with hat on top Point space straight E equals negative 0.6 straight i with hat on top plus 0 straight j with hat on top minus 2.25 straight k with hat on top Point space straight D equals 1.2 straight i with hat on top plus 0 straight j with hat on top minus 2.25 straight k with hat on top Distance space AE with rightwards harpoon with barb upwards on top equals open parentheses negative 0.6 straight i with hat on top plus 0 straight j with hat on top minus 2.25 straight k with hat on top close parentheses minus open parentheses 0 straight i with hat on top plus 2.9 straight j with hat on top plus 0 straight k with hat on top close parentheses space AE with rightwards harpoon with barb upwards on top equals negative 0.6 straight i with hat on top minus 2.9 straight j with hat on top minus 2.25 straight k with hat on top Similarly comma AD with rightwards harpoon with barb upwards on top equals 1.2 straight i with hat on top minus 2.9 straight j with hat on top minus 2.25 straight k with hat on top
