Answer:
∴ The measure of the remainder of the circle = 248°
Step-by-step explanation:
∵ The measure of the circle = 360°
∵ The measure of the minor arc = 112°
∴ The measure of the remainder of the circle = 360 - 112 = 248°
Answer:
x ( x -1 )
Step-by-step explanation:
Answer:
Ruler: £0.90
Pencil: £0.60
Step-by-step explanation:
Ruler = x
Pencil = y
2x + y = 2.4
5x + y = 5.1
3x = 2.7
x = 0.9
y = 0.6
Answer:
(x, y ) → (- y, - x )
Step-by-step explanation:
Consider the coordinates of corresponding vertices of the 2 triangles, that is
A(1, 7 ) → D(- 7, - 1 )
Note the coordinates of D are the negative reversals of A
Thus (x, y ) → (- y, - x )
