In a triangle abc if r1 2r2 3r3
WebUsually with matrices you want to get 1s along the diagonal, so the usual method is to make the upper left most entry 1 by dividing that row by whatever that upper left entry is. So say the first row is 3 7 5 1. you would divide the whole row by 3 and it would become 1 7/3 5/3 1/3. From there you use the first row to make the first column have ...

WebStep 2: Determine the ratio. Since two angles are equal, the triangle is an isosceles right angle triangle and hence two sides will be equal. Therefore let sides a = k, b = k. Thus we have, by the converse of Pythagoras theorem. c = a 2 + b 2 = k 2 + k 2 = 2 k 2 c = 2 k. The ratio of a: b: c is 1 k: 1 k: 2 k o r 1: 1: 2. WebMar 19, 2024 · Add a comment 1 Answer Sorted by: 0 Cauchy-Schwarz, or just ( a − b) 2 ≥ 0, implies a 2 + b 2 ≥ 2 a b, and so on for b, c and c, a. Add them all up we got 2 ( a 2 + b 2 + c 2) ≥ 2 ( a b + b c + c a), which means a b + b c + c a a 2 + b 2 + c 2 ≤ 1. That would solve your last step.
