The equation which represents the above situation algebraically isa) 2 + 7 − 120 = 0 b) 2 + 5 − 120 = 0c) 82 + 7 − 120 = 0d) 2 + 2 − 120 = 0​

Answer»

The road from Alwah to Chagotar, is exactly perpendicular to the road going from CHAGOTKAR to Barogh. The distance covered by the road between Chagotkar and Barogh is 7 kilometers more that the distance of the road connecting Alwah and Chagotkar. Ayushi is an engineer looking after the project of building a direct bypass road that would connect Alwah and Barogh and has proposed to construct a 17 KM direct bypass road between the two cities. To Find : The equation which represents the above situation algebraically is-a) x² + 7x − 120 = 0b) x² + 5X − 120 = 0c) 8x² + 7x − 120 = 0d) x² + 2x − 120 = 0​  Solution :  Pythagoras' THEOREM: square on the hypotenuse of a right-angled TRIANGLE is equal to the sum of the squares of the other two perpendicular sides. x² + (x + 7)² = 17²=> x² + x² + 14x + 49 = 289=> 2x² + 14x - 240 = 0=> x² + 7x - 120 = 0  x² + 7x − 120 = 0  represents the   situation algebraicallyLearn More:The equation which represents the above situation algebraically brainly.in/question/35148081The equation which represents the above situation algebraically i brainly.in/question/35407747
