The measures of two angles of ABC (shown in the illustration) are given. Find the measure of the third angle, if  m(∠A) = 130.3º and m(∠B) = 40.3º.  

Consider the decomposition of bromochloride to produce elemental bromine and elemental chlorine at a particular temperature:                                        2 BrCl(g)   ⇌   Br2(g)  +  Cl2(g)         KP = 81.0 A closed vessel is charged with 3.00 atm of BrCl initially and allowed to reach equilibrium. What is the partial pressure of the Br2 (in atm) at that equilibrium?
