Everything you're posting involves right triangles, and
each one is solved with the Pythagorean formula:

              (one leg)² + (other leg)² = (hypotenuse)²

For the tree . . .
Do you see the right triangle ?
They even marked a little box at the base of the stump
to remind you that there's a right angle there.

-- The stump is 3 meters high.
-- The broken part of the tree is on the ground
    13 meters away from the stump.
--  The broken part of the tree is the hypotenuse.
       (3)² + (13)² = (broken part)²

-- Before it fell over, the broken part stood on top of the 3-meter stump.

==========================================

#4).  Your coordinates for point 'G' are correct, but
the coordinates of point 'F' should be (-1, 6), not (1,6).
If you know how to calculate the distance between 2 points,
then that little correction might fix the problem you're having.

The distance between two points is

        Square root of [ (x₁-x₂)² + (y₁-y₂)² ]
or
       Square root of [ (difference of the x's)² + (difference of the y's)² ] .

Without even using this formula, you could just look at
the graph, and do something like this:

-- From 'F', draw a line 2 units straight down.

-- From 'G', draw a line 4 units to the left.

-- Connect 'F' and 'G' .

Now you have a little right triangle.
The legs are 2 units and 4 units.
The hypotenuse is the distance between 'F' and 'G'.

   (2)² + (4)² = (that distance)²

Answer:

5

Step-by-step explanation:

Since this is a right triangle we can use trig functions

sin theta = opp /hyp

sin 30 = x / 10

10 sin 30 = x

10 * 1/2 = x

5 =x

Find the slope of the line that passes through the pair of points listed below.
Tresset [83]

Answer:

Step-by-step explanation:

(-2,-4),(-1.5, -1.5)

y2 = -1.5, y1 = -4, x2 = -1.5, x1 = -2

Slope m = (y2 - y1)/(x2 - x1)

m = (-1.5 + 4)/(-1.5 + 2)

m = 2.5/0.5

m = 5
