Answer:
m∠BCD = 140°
Step-by-step explanation:
ABCD is cyclic quadrilateral. A property of cyclic quadrilateral states that the opposite angles of it sum up to 180°. Here:
m∠A + m∠C =180° and m∠B + m∠D = 180°
So, m∠A + m∠C =180°
m∠A = 40° (given in the question)
40° + m∠C = 180°
m∠C = 180° - 40° = 140°
∴m∠C = m∠BCD = 140°
Answer:
714
Step-by-step explanation:
So lets go over what we know.
The bus only goes for 6 hours each day.
So lets just think of a full day as 6 hours.
Each day(6 hours), 4284 passangers ride the bus.
To find passangers per hour, we must divide the total passangers by the total hours.
This is 4284(total passangers) divided by 6(total hours):
4284/6
=
714
So each hour, there are 714 passangers.
Hope this helps!
Answer:
See below.
Step-by-step explanation:
If it is a regular polygon then you can look up the formula or break it into shapes you do know the formula.
If it is irregular or a composite figure, break it into regular polygons which do have formulas to find the area. Here is an example:
Example:
Find the area of the composite figure by splitting the figure into two shapes - two rectangles.
One rectangle is 2 x 9 = 18.
The other rectangle is 2 x 4 = 8.
Together the area is 18 + 8 = 26.
Answer:
y = -4x - 11.
Step-by-step explanation:
Its slope = slope of y = -4x + 2, which is -4.
Using point-slope form of a straight line
y - y1 = m(x - x1)
y - (-3) = -4(x - (-2))
y + 3 = -4(x + 2)
y = -4x - 8 - 3
y = -4x - 11.
I'm not sure what the answers are, but I can help. If you go to the x axis and search for 50, then go straight up to the line of best fit, you'll find the estimated height of the tree. It appears to be about 70.
Hope this helps!
