In the figure above, if a:b:c = 3:4:1, what is the value of a?
Darina [25.2K]

Answer:

30

Step-by-step explanation:

The line is divided up into 3 parts, a part of 3, a part of 4, and a part of 1.  If we had those parts together we get 8 meaning if we divided the line into equal parts that also fit into a, b, and c there would be 8.  We can than divide the line into 8 parts which would be 10 each since a line is 180 degrees.  Since a is 3 than a gets 3 of those parts meaning a would be 30

I hope this helps and please don't hesitate to ask if there is anything still unclear!

The midpoint of line segment AB is (-2,1). If the coordinates of B are (0,2) what are the coordinates of A?
Whitepunk [10]

The required coordinate of A will be at (-4, 0)

When a point bisects a line, it cuts the line into two equal parts and the point on that line is known as its midpoint. The expression for calculating the midpoint of a line is expressed as;

M(X, Y)= [{ \frac{x_2+x_1}{2} , \frac{y_2+y_1}{2} ] where:

X =\frac{x_2+x_1}{2} \\Y=\frac{y_2+y_1}{2}

From the question, we are given the following coordinate points

X=-2\\x_1=0\\

Get x₂;

X =\frac{x_2+x_1}{2}\\-2 =\frac{x_2+0}{2}\\2 \times -2=x_2+0\\-4=x_2\\ Swap\\x_2=-4\\

Get y₂;

Y =\frac{y_2+y_1}{2}\\1 =\frac{y_2+2}{2}\\2 \times 1=y_2+2\\2=y_2+2\\y_2=2-2\\y_2=0

Hence the coordinate of A will be (-4, 0)
