Question

plz solve this problem with explanations ​

Answer 1

Step-by-step explanation:

angle x + angle y + angle w + angle z

make 360 degree angle that proves that aob is a line

Answer 2

Answer:

we know that x+y+z+w = 360 {complete angle }--------(1)

∵x+y=w+z-----------(2)

using 2 in 1

x+y+x+y=360

2x+2y=360

2(x+y)=360

x+y=360/2

x=y=180

since x and y form a linear pair on AOB

so AOB is a line
