Find the distance from point A(−1, 7) to the line y=3x. Round your answer to the nearest tenth.
bearhunter [10]

Answer:

<em>The distance from the point to the line is approximately 3.2 units</em>

Step-by-step explanation:

<u>Distance From a Point to a Line</u>

Is the shortest distance from a given point to any point on an infinite straight line. The shortest distance occurs when the segment from the point and the line are perpendiculars.

If the line is given by the equation ax + by + c = 0, where a, b and c are real constants, the distance from the line to a point (x0,y0) is

\displaystyle d= \frac{|ax_0+by_0+c|}{\sqrt{a^2+b^2}}

The line is given by the equation:

y=3x. We need to transform it into the specified form.

Subtracting 3x:

y - 3x = 0

Comparing with the general form of the line, we have

a=-3, b=1, c=0

The point (xo,yo) is (-1,7), thus:

\displaystyle d= \frac{|-3\cdot (-1)+1\cdot 7+0|}{\sqrt{(-3)^2+1^2}}

\displaystyle d= \frac{|3+7|}{\sqrt{9+1}}

\displaystyle d= \frac{|10|}{\sqrt{10}}

\displaystyle d= \frac{10}{\sqrt{10}}

d\approx 3.2

The distance from the point to the line is approximately 3.2 units

One of the same side angles of two parallel lines is 20° smaller than the other one. Find the measures of these two angles.
Norma-Jean [14]

Answer:

The measure of these two angles are 80° and 100°

Step-by-step explanation:

Let

x and y ----> the measure of the same side angles

we know that

The sum of of the same side angles of two parallel lines is equal to 180 degrees

x+y=180° -----> equation A

x=y-20° ----> equation B

substitute equation B in equation A and solve for y

(y-20°)+y=180°

2y=180°+20°

y=200°/2

y=100°

Find the value of x

x=100°-20°=80°
