how pls tell this I have exam I am preparing​

Answer 1

Answer:

(a) 120⁰

Step-by-step explanation:

A/Q

Lines l || m,

Thus, 60⁰ and angle z are co-interior angles.

Since, 60⁰+z = 180⁰

Hence, z = 180⁰-60⁰ = 120⁰

Answer 2

Answer:

Answer is 120

Step-by-step explanation:

Because one angle is given 60’ then the opposite angle will be same to 60'

60 +60 = 120

360- 120 = 240

then 240/2= 120

so, the angle z will 120 degree
