Answer:
z = 100°
x = 40°
Step-by-step explanation:
Triangle CBD is isosceles so there are two 50°
DBC = 50°
That means BDC = 80° because 180(sum of angles in triangle) - 50 - 50 = 80
Z = 100° bc angle of straight line is 180° and 180 - 80 = 100
Now triangle ADB is also isosceles because there are two sides of equal length
So there will be 2*x + 100 = 180
x = 40°
