Answer 1

Answer:

x = 120°

Step-by-step explanation:

x = angleCBD + angleBCD (Exterior Angle Property)

angleABD = 180 - (angleBAD + angle ADB) [Angle Sum Property]

angleABD = 180 - (55 + 25) = 180 - 80 = 100°

Now,

angleCBD = 180 - angle ABD (Linear Pair)

angleCBD = 180 - 100 = 80°

So,

x = 80 + 40 = 120°
