we didn't given that hit it equal to 3.6 b equals toe 6.2 and C equals to 4.1. All the sides are given So this is a drink Goes here. Now we have to solve for the Ringel. So this is a be candidacy. So this will be a This will really small way The Saluzzi putting the values 3.6 this is 6.2. This is for going toe Enough. We have to find all the angles So for this way have to solve it like this Off a equals two is good minus here minus b squid. Let's see a square dueted with no people do we see? So by quitting that we get be square policies were minus is going to end with obesity So now for course be this will be again a square. Let's see a squared minus b squared. Do you have it to a C Now, for course, this will be B squared. Plus sees their minus is where do other work to B. C. Put these values and get so this will be so now putting this value will be 38.44 They were everything. 2.8 for now. Following this weekend Little burnt stone 56 Now similarly, by solving this all we get this will you on by some 11.49. 0.832 So everything we are left with yet course a equals 2.756 Now close B equals two point for 39 course C equals two point. So now we will. Getting here here equals two course in words. Buoyant, stolen 56 b equals toe course in words were 39 439 No see Wolf two course in work. Little 0.83 toe vice away We get equals toe Really good. 41.25 degrees and selling this equation because the constant airport 14 and we get 64.4 degrees. Now. When we saw of course, it was pointed to get 34.3. So these are the three angles and these are the misery went up to size. Does we have sold a drink
