Step-by-step explanation:
(3x+5)°+(2x+5)°+(y+10)° = 180° (∆abc)
5x+y+20 = 180°
5x+y = 160° -------> (1)
(y+10)°+(y+20)°+(3x+5)° = 180° (∆bda)
2y+3x+35 = 180°
2y+3x = 145° --------> (2)
comparing (1)&(2)
-2(5x+y=160)
5(2x+3y=145)
----------------
-10x-2y = -320
10x+15y= 725
-----------------
13y = 405
y = 31.1° approx
5x+(31) = 160
5x. = 129
x = 25.8°
