Question

Holaa,Brainliars!!♡
Sry fr asking many questions!!..thts becoz i hv my exam..!!✌

In the fig. given:
AB||CD
To Find:
•Value of z
And
•Value of Angle DNM & Angle CNM

Answer 1

3z-42=2z+13
z=55
so angle <DNM=110+13
=123
&<CNM= 180-123
=57

Answer 2

3z-42=2z+13(Alternate interior angles)
3z-2z=13+42
1z=55
z=55.
substitute the value of 'z' in angle DNM
2×55+13
=123
Angle DNM+Angle CNM=180(linear pair)
123+CNM=180
CNM=180-123
CNM=57
Hope this will help u
