Question

in the given figure ablldc find the value of x,y,z​

Answer 1

Answer:

x=35(// quadrilateral's alternate angle)

triangle's sum of angle =180

80+x+y=180

80+35+y=180

115+y=180

y=180-115

y=65

angle/CBD= y- 30

65-30=35

Answer 2

Step-by-step explanation:

x = 35 ° ( angle CDB = angle DBA alternate angle)

In ΔABD

angle A = 80°

angle ABD = x and angle ADB = y

x + y + 80° = 180

x + y = 100°

y = 100 - x

In ΔBCD

z + y - 30 °+ 35° = 180°

z + y = 175°

y = 175 - z

100 - x = 175 - z

z - x = 75 °

z = 75 + 35

z = 110 °

y = 100 - 35

y = 65°
