1 centimeter = 3 meters. A rectangle with length 7 centimeters and width 1.75 centimeters.

1 answer:

3 0

Answer:

The length if the garden is 21 meters.

The width of the garden is 5.25 meters.

If the scale changes to 1 cm : 9 meters, the new length of the garden is 63 meters and the new width of the garden is 15.75 meters.

The new length of the garden is 3 times as long as the original length of the garden.

Answer:

Side c:

If angle A is 90 degrees, side a is the hypotenuse.
$c^{2} + b^{2} = a^{2}$ <--- this is NOT the correct way to write the Pythagorean theorem. I changed it to fit the side lengths. Normally, it is $a^{2} + b^{2} = c^{2}$ , where c is the hypotenuse. Since a is the hypotenuse, I switched the variables.
$c^{2} + (1)^{2} = (2)^{2}$
$c^{2} + 1 = 4$
$c^{2} = 3$
$c = \sqrt{3}$

Finding the angles:

In a 30-60-90 right triangle, the...
Shortest leg = x
Longest leg = $x\sqrt{3}$
Hypotenuse = 2x
In this case, the shortest leg is 1, the longer leg is $\sqrt{3}$ (or $1*\sqrt{3}$ ), and the hypotenuse is 2 (or $2*1$ ).
As a result, this is a 30-60-90 triangle -- angle B is 30 degrees while angle C is 60 degrees.
