Part A)
Using the Pythagorean theorem you can find the height:
17^2 = 8^2 + x^2
289 = 64 +x^2
x^2 = 289 - 64
x^2 = 225
x = √225
x = 15
The height is 15 cm.
Part B)
Area of the triangular side: 1/2 x 16 x 15 = 120 square cm.
There are two triangles so 120 x 2 = 240 square cm.
One side = 20 x 17 = 340
There are 2 sides so 340 x 2 = 680 square cm.
The bottom is 16 x 20 = 320 square cm.
Total cardboard needed: 240 + 680 + 320 = 1,240 square cm.
Hey there! I'm happy to help!
We want to get c all by itself on one side of the equation. Usually variables go on the left side, so let's flip the equation around.
c/9=-8
If we multiply c/9 by 9, the 9 will cancel out because if you divide by 9 and then multiply by 9 it just equals 1. We can do this to isolate the c, but whatever you do to one side of the equation, you have to do to the other. So, we multiply both sides by 9.
c/9×9=-8×9
c=-72
Have a wonderful day! :D

Whole numbers are reasonable to describe the number of desk.
The length of each side of the polygon is the number of units on each side of the polygon, and the perimeter of the factory is 1000 feet
<h3>The length of each side of the polygon?</h3>
To do this, we simply calculate the number of units on each side of the polygon.
So, we have:
S1 = 5 units
S2 = 8 units
N1 = 13 units
E1 = 7 units
W1 = 3 units
W2 = 4 units
<h3>The perimeter of the polygon</h3>
This is the sum of the side lengths.
So, we have:
Perimeter = 5 + 8 + 13 + 7 + 3 + 4
Perimeter = 40
Each unit equals 25 feet.
So, we have:
Perimeter = 40 * 25 feet
Evaluate
Perimeter = 1000 feet
Hence, the perimeter of the factor is 1000 feet
