we are given

we can use vertex form parabola formula

so, we can complete x square




so, option-A........................Answer
Answer: The answer is 6.28571 . . ..
Step-by-step explanation: We are given ti find the value of twice of pi into the palette.
We are familiar with the irrational number pi. It is defined as the ration of circumference of a circle to the diameter of the circle and its value is 22/7 or 3.14159 . . ..
Therefore, the value of 2 pi can be calculated as follows.

Thus, the value of 2pi is 6.28571 . . ..
<span>Simplify and you will get -111</span>
By geometrical inspection we have:
M4 = 30
Then the angle M6 can be determined from the fact that you have a rectangle triangle (345) that has an angle of 90 and another of 30. The missing angle measures:
180-90-30 = 60 = M3
Then to find M6 we have
M3 + 60 + M6 = 180
M6 = 180-60-M3
M6 = 180-60-60
M6 = 60
answer:
M4 = 30
M6 = 60
