Question

Please solve it with steps​

Answer 1

Answer:

y=70,x=60,z=60

Step-by-step explanation:

in∆DCM

y=180-(20+90)=70

in ∆DMA

x=180-(30+90)=60

∆DMA is congruent to ∆CNB

z=x=60(cpct)

Answer 2

in triangle DMC;

since Dm is perpendicular AC Angle Dnc=90°

:: y°= 180-(90+20)

=180-110

=70°

x°= 180-(90+30)

= 180- 120

=60°

:: triangle DMA congruent to triangle CNB(RHS)

by cpct;

z=x(60°)
