10/4 is not the simplified version that it can be. So 5/2 would be the same expression.
2,3,3,4
This is just anything right here
sorry I'm in 5 grade idc what that is tho
step 2 would be 10
step 4 would be 10x-x = 9x =7
x = 7/9
Answer:
As Given, x+y=w+z
To Prove: AOB is a line or x+y=180
∘
(linear pair.)
According to the question,
x+y+w+z=360
∘
∣ Angles around a point.
(x+y)+(w+z)=360
∘
(x+y)+(x+y)=360
∘
∣ Given x+y=w+z
2(x+y)=360
∘
(x+y)=180
∘
Hence, x+y makes a linear pair.
Therefore, AOB is a straight line
