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

Find the surface area of the tool box. Round your answer to the nearest tenth and explain your answer. ​Pls I NEED THE ANSWER NO
Andrej [43]

Answer:

807.8 in^2

Step-by-step explanation:

The total area of the box is the sum of the areas of all faces of the box. The top, bottom, front, and back faces are rectangles 18 in long. The end faces each consist of a rectangle and a triangle. We can compute the sum of these like this:

The areas of top, bottom, front, and back add up to be 18 inches wide by the length that is the perimeter of the end: 2·5in +2·8 in + 9.6 in = 35.8 in. That lateral area is ...

(18 in)(35.6 in) = 640.8 in^2

The area of the triangle on each end is equivalent to the area of a rectangle half as high, so we can compute the area of each end as ...

(9.6 in)(8.7 in) = 83.52 in^2

Then the total area is the lateral area plus the area of the two ends:

640.8 in^2 + 2·83.52 in^2 = 807.84 in^2 ≈ 807.8 in^2
