In triangle ABC, the side lengths are AB = 13, AC = 21, and BC = x. Write a compound inequality that represents the range of pos

N76 [4]

There is only 1 solution for the length of BC.

We can calculate it using Pythagorean theorem.

We can conclude that triangle's hypotenuse is AC.

$AC^2=AB^2+BC^2$

If that is the case we are looking for a side BC.

$BC=\sqrt{AC^2-AB^2}$

Now put in the data.

$BC=\sqrt{21^2-13^2}=\sqrt{272}=\sqrt{272}\approx\boxed{16.49}$

Hope this helps.

Write a equation of a line that is perpendicular to y = -2/7x+9and pass through point (4,-6)

nikitadnepr [17]

Answer:

y = 7/2x - 20.

Step-by-step explanation:

The slope of the given line is -2/7, therefore the slope of the line perpendicular to it is - 1/ -2/7 = 7/2.

When x = -4, y = -6 so we substitute x1 = 4, y1 = -6 and m ( the slope) = 7/2 in the point slope form of a line:

y - y1 = m(x - x1)

y - (-6) = 7/2(x - 4)

y + 6 = 7/2x - 14

y = 7/2x - 20.
