Angle A is supplementary with angle C, thus, by the Inscribed Angle Theorem:
Answer:
Given:
To calculate how many electrons have the same mass as one dust particle, divide the mass of a dust particle by the mass of an electron:
Therefore, approximately electrons have the same mass as one dust particle.
The point-slope equation of the line is y-2=-2(x-7)
How will we find the equation of line?
First, we will find the slope of line using the given points then put slope and point in the formula to get equation of line.
We can find the equation as shown below:
Given points (6,4) and (7,2)
slope(m)= (2-4)/ (7-6)
m=-2/1
m=-2
The point slope form:
(y-y1) = m(x-x1)
y1=2, x1=7
putting in formula
(y-2) = -2(x-7)
y-2=-2(x-7)
Hence, the point-slope equation of the line is y-2=-2(x-7)
