WebParts of a triangle. All triangles are made up of three sides and three angles. The point at which two sides of a triangle meet is referred to as a vertex. Triangles are commonly … WebCorrect option is B) Given that r 1r 2r 3 are radii of ex-circles, we have the following relations r 1= s−aΔ,r 2= s−bΔ,r 3= s−cΔ where Δ is the area of the triangle ABC having lengths of the sides a,b,c and 2s= a+b+c Also given r 1=2r 2=3r 3 So r 2r 1=2 ⇒ s−as−b=2 ⇒s−b−2s=−2a ⇒s+b−2a=0 ⇒2s+2b−4a=0 ⇒a+b+c+2b−4a=0 ⇒c+3b−3a=0 ⇒c+3b−3a=0 ⇒c=3a−3b
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 ...
