Am not understanding kiswahili

My apologies, Mericah! I will switch to English for you. Let's re-do that question. Guidance for Power Distribution Project (ITEM 1): Step 1: Calculate the length of the distribution lines. From the given data, we have the position vectors: OA = 2i + 3j OB = 10i + 9j OC = 14i + 5j The vector for the line from substation A to village B is: AB = OB - OA = (10-2)i + (9-3)j = 8i + 6j The length of the distribution line AB is: |AB| = sqrt(8^2 + 6^2) = sqrt(64 + 36) = sqrt(100) = 10 km The vector for the line from substation A to village C is: AC = OC - OA = (14-2)i + (5-3)j = 12i + 2j The length of the distribution line AC is: |AC| = sqrt(12^2 + 2^2) = sqrt(144 + 4) = sqrt(148) = 2sqrt(37) km ≈ 12.17 km Step 2: Calculate the angle between the distribution lines AB and AC. We use the dot product formula: AB · AC = |AB| |AC| . AB · AC = (8)(12) + (6)(2) = 96 + 12 = 108 = (108)/(10 · 2sqrt(37)) = (108)/(20sqrt(37)) = (27)/(5sqrt(37)) = ((27)/(5sqrt(37))) ≈ 27.4^ The requirement is that the angle between the two distribution lines from the substation must be less than 45^. Since 27.4^ < 45^, this condition is met. Step 3: Determine the appropriate angle of inclination for the distribution line from A to B. The engineer used the equation 4^2 - 3 = 0 to represent the inclination of the distribution line from A to B. 4^2 = 3 ^2 = (3)/(4) = ±sqrt((3)/(4)) = ±sqrt(3)2 Case 1: = sqrt(3)2 This gives = 60^ or = 180^ - 60^ = 120^. Case 2: = -sqrt(3)2 This gives = 180^ + 60^ = 240^ or = 360^ - 60^ = 300^. The possible values for are 60^, 120^, 240^, 300^. The distribution line from A to B has vector AB = 8i + 6j, which points into the first quadrant (positive slope). Therefore, its angle of inclination should be between 0^ and 90^. Among the values found, only 60^ is in the first quadrant. Summary of Guidance: The length of the distribution line from substation A to village B is 10 km. The length of the distribution line from substation A to village C is 2sqrt(37) km. The angle between the distribution lines AB and AC at substation A is approximately 27.4^, which satisfies the condition of being less than 45^. Based on the engineer's system, the appropriate angle of inclination for the distribution line from substation A to village B is 60^. That's 2 down. 3 left today — send the next one.
