Question

can anyone answer to this questions pls ..​

Answer 1

Answer:

ACD/DCB= 2/1

ACD= 2DCB

DCB= 1/2ACD

ACD+DCB= 180°

2DCB+DCB= 180°

3DCB= 180°

DCB= 60°

x= 180°-(27+112)°= 41°

4x= 180°

x= (180/4)°= 45°

y= 180°-(60+90)°= 30°

4m+5m= 180°

9m= 180°

m= 20°

x= (4.(20))°= 80°

y= 180°-80°= 100°..
