Question

Plz solve this asap I’ll mark as brainliest

Answer 1

Step-by-step explanation:

i)31+90+y=180

121+y=180

y=180+121

y=59 degree

x=31 degree (vertically opposite angles)

ii) z=51 degree

x=44 degree

51+44+y=180

95+y=180

y=85 degree

Answer 2

Answer:

(i)'y' may be 40° and 'x' may be again 40°.

(ii)'x' maybe 80° , 'y' maybe 50° and 'z' maybe 50°.

Step-by-step explanation:

In angle one 'x' and 'y' are on a same line that just mean that it  a linear pair the measure of the linear pair is 180° so the same comes in second case.
