Answer» Answer: Step-by-step explanation: Angle a = x+30 Angle b = 3x+25 Angle ACD = 5x-5 According to exterior angle property: ACD = a=b 5x-5 = x+30 + 3x + 25 5x-5 = 4x + 55 5x-4x = 55+5 x= 60 Angle b = 3*60 +25 Angle b = 180 + 25 Angle b = 205 Hoping that it will HELP you and if it does then PLEASE LIKE it and follow me. |
