The product of the -72 could be set up at -72=-9(x).
Divide -9 from both sides and you get the unknown value (x) to be 8
Answer:
A = 22 degrees
Step-by-step explanation:
ABC is a right angle triangle, and angle ACB=68 degrees
hence, the angle BAC or angle A = 90-68 = 22 degrees
These statistics compare the population density of these countries.
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
