In the figure a transversal cuts two lines m and n. The co-interior angles on the right are 5z deg and 4z deg. If it is given that the lines do NOT meet anywhere (they are parallel), find z and hence the value of 5z.

Question

Accepted Answer

100. Parallel means co-interior sum = 180: 5z + 4z = 180, 9z = 180, z = 20. So 5z = 100°.

In the figure a transversal cuts two lines m and n. The co-interior angles on the right are $5 z$ deg and $4 z$ deg.
If it is given that the lines do NOT meet anywhere (they are parallel), find $z$ and hence the value of $5 z$ .
