Answer:
Step-by-step explanation:
We have been given two points on a line and
. We are asked to write an equation passing through these points.
We will write our equation in slope-intercept form of equation , where,
m = Slope of line,
b = Initial value or the y-intercept.
Let us find slope of given line using slope formula.
Let point and point
.
Now, we will substitute and coordinates of point
in slope-intercept form of equation as:
Upon substituting and
in slope-intercept form of equation, we will get our required equation as:
Therefore, our required equation would be .
Answer:
12.43ft
Step-by-step explanation:
From the given diagram, we simply apply the sin rule
According to the sine rule
=
y is the side y
y° = (90 - 43) = 47
z = 17
z° = 90
Input the parameters and solve;
ysin 90 = 17 sin 47
y = 12.43ft
