please help!

 

Just add them all up and solve for x.          x   +   6x   +   (x + 4)  =  180  

                                                                                       8x + 4   =  180  

                                                                                       8x         =  180 – 4   =  176     

                                                                                               x   =  22  

 

So ....                         x  =    22^o  

                                6x  =  132^o  

                          (x + 4)  =   26^o  

_.

x+6x+x+4=180

8x+4=180

8x=176

x=22, 6x=132, and x+4=26 this is our final answer.
