What is the measure of angle A in the triangle shown above?
                                             
                                          
                                          
                                        
											 
											Answer:
answer is A
sum of angles = 180
5x -20 + 3x +5 + 2x - 15 =180
10x = 180 + 30
10x=210
x=21
A=3×21+5
=68
