Answer:
Significant Figures are the figures in a number that are meaningful and are digits with no zeros. Those zeros can be traced in a number like <em><u>“</u></em><em><u>3</u></em><em><u>2</u></em><em><u>0</u></em><em><u>”</u></em>, or <em><u>“</u></em><em><u>5</u></em><em><u>6</u></em><em><u>7</u></em><em><u>0</u></em><em><u>.</u></em><em><u>0</u></em><em><u>0</u></em><em><u>4</u></em><em><u>5</u></em><em><u>”</u></em>. Those zeros are not counted when counting the significant figures.
I hope you understand.
FALSE it will not because there are two points with the same X value
The required value of Arc BC m = 140° Option B is correct.
Given that,
AD is the diameter of the circle,
∠1 = ∠3 = 20°
Arc BC is to be determined.
<h3>What is an arc?</h3>
Arc is the measure of angle on the circumference of circle.
Here,
∠1 = arc AB
∠3 = arc CD
Now, for circle p
Since angle 1 and angle 2 are equal to the composition of the arc,
Arc AD = Arc AB + Arc BC + Arc CD = 180
20 + Arc BC + 20 = 180
Arc BC = 180 - 40
Arc BC = 140°
Thus, the required value of Arc BC m = 140° Option B is correct.
