they asked us all the falling to Ringo. Use any table form so it's are a little too strong other people. So we only need to find the angles. Sorry. In so based off of that we can, you know, that are different angles. We have ankles. Really? If you know 30 degrees B which we do not know yet see which we do not know yet then we have size a which we don't know yet the which we don't know yet and see which is to go 296 centimeters. Doctor, would you? No ankle? See? It is 90 degrees and so first. Well, we can start by finding and GOP so another angle B is equal to 180 police minus 30 degrees minus nine degrees which gets us 180 minus 1 20 which gets a 60 degrees in Gobi. So now that we have found all the angles we can use are treatment magic identities to find everything else. So first of all, when we can first find a so we have signed off, a 30 is equal to opposite over adjacent do that A is equal to sign of 30 turns 196 and that will get us so we can pluck that ensure calculator. So you sign of 30. It's 196 which gets us A is equal to 98. So we heard 98 and last Not least so, for, you know, is equal to 98. Then when we saw for B does use the Pythagorean idiom. So we have a squared plus B squared people to see square. So we know that 98 squared plus B squared is equal to 196 squared. So it's attractive 196 scored from 98 squared. That will get us. He scored equal 269.7. We're sorry we scored is equal to to 20,812 So therefore B is equal to 169.74 approximately. So get beat. Does he go to 169? 169 0.74 This is our answer
