Find the distance between each pair of points
densk [106]

Answer:

Use Distance Formula

Step-by-step explanation:

You can find the distance between two points by using the distance formula which by definition is \sqrt{(x_2-x_1 )^2+(y_2-y_1)^2 }

For example take question 3. Plug your point values in to find the distance

Point 1 is (-1, 8)

Point 2 is (-3, -2)

You equation would look like:

\sqrt{(-3-(-1))^2+(-2-8)^2}

This simplifies to \sqrt{(-2)^2+(-10)^2}

=\sqrt{4+100}

=\sqrt{104}

=\sqrt{2(2)(26)}

=2\sqrt{26}

That is the distance between the points (-1, 8) and (-3, -2)

Answer:

  • 5.4 m

Step-by-step explanation:

<u>Given </u>

  • The top of the tree, the point A and the base form a right triangle
  • Horizontal leg = 8 m
  • Vertical leg = the height of the tree = x
  • Angle A = 34° is opposite to the three

<u>Use the ratio to find the value of x:</u>

  • opposite / adjacent = tan A
  • x/8 = tan 34°
  • x = 8 tan 34 degree
  • x = 5.4 m (rounded)
