x = 8
y = 40 

the two base angles are equal to each other so you would do 5x = 40 and solve for x

a triangle has 180 total degrees. 40*2 = 80 
                                                       180 - 80 = 100
                                                    2y + 20 = 100
                                                    2y = 80
                                                     y = 40
