Answer:
C
Step-by-step explanation:
yx can be rearranged to xy
it's like saying 2 x 3 is the same as 3 x 2
xy or yx is the variable
y= (1, 4) times x + (15, 4)
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
X=1. Chose C. Hoped that will help
