The slope and y-intercept values indicate characteristics of the relationship between the two variables x and y. The slope indicates the rate of change in y per unit change in x. The y-intercept indicates the y-value when the x-value is 0.
We have to form a quadrilateral by connecting the midpoints of the square.
The side of the square: a.
The side of the new quadrilateral: x² = (a/2)² + (a/2)²
x² = a²/4 + a²/4 = a²/2
x = a√2 / 2
All sides of the quadrilateral are equal: a√2 / 2.
So it could be another square or a rhombus. But all interior angles of the new quadrilateral are the same: 90°.
Answer: This is the square.
Average of 2 numbers is 40
so total = 2 x 40 = 80
300 - 80 = 220
average of remaining 10 numbers = 220/10 = 22
answer
B) 22
A shape with 4 angles always have 360 degrees altogether.
Which means:
43 + 167 + 90 + y = 360
y = 360 - 43 - 167 - 90
y = 60
