The top-left one because 3ba is the same as 3ab
Answer:
The angle = 144 degrees.
Step-by-step explanation:
Look at it this way (it is a proportion question)
30 people would require a pie chart made of a full circle (360 degrees)
12 people would require x part of the pie chart.
30/360 = 12 / x Cross multiply
30x = 360 * 12 Simplify the right
30x = 4320 Divide by 30
30x/30 = 4320/20
x = 144 Answer
Assuming you mean
, which is the equation of a circle :
the general equation of a circle of radius
and center
is
hence here the center is
Answer:
y = -x -7
Step-by-step explanation:
Use point slope
y − y1 = m(x − x1)
y - (-5) = (-1)(x-(-2))
y + 5 = -x -2
y = -x -7
Well 7x4=28 right?
So what is 2/7 of 28?
