Step-by-step explanation:
Answer:
(Opt.B) 18
Step-by-step explanation:
4x = 2y - x (vertically opposite angles are equal)
4x + x = 2y
5x = 2y ----- (1)
4x + 2y + x = 180 (Linear pair angles)
5x + 2y = 180
From (1) we can understand that, the value of 5x and 2y is the same. So,
5x + 5x = 180
10x = 180
x = 180/10
x = 18
Just completing,
Putting the value of x in (1)
5*18 = 2y
90 = 2y
90/2 = y
45 = y

4. Answer: 1/9
Answer: 9 cm
Step-by-step explanation:
The formula of the area of a square is
A = s²
The ‘A‘ stands for area and the ‘s’ stands for side measure.
Now, since you already know the side measure, it’s 3cm, you just have to put it into the equation.
So, now you have:
A = 3²
A = 9
Therefore, the area of the square is 9 cm.
