Question

hi pls help me in this this is maths​

Answer 1

Answer:

x =80 and y =40

Step-by-step explanation:

Angle ACD +x =180

... (linear pair angles)

100+x=180

x =180-100=80

Angle ADE + Angle ADC=180

120+Angle ADC =180

Angle ADC =180-120=60

x+y+Angle ADC=180

.... (Property of triangle)

80+y+60=180

y=180-140=40
