The five is the digit in the hundredths place<span />
Answer:
98
Step-by-step explanation:
Total units of ratio = 2+4+4 = 10
value of 1 unit = 180/10 = 18
angles would be: 2(18), 4(18), 4(18) = 36, 72 & 72
Answer:
Explanation contains the proof.
Step-by-step explanation:
.
.
We want to show that . So we are asked to show that there exist integer
So what is ?
.
.
So back to ....
(I use foil to get this)
Factoring out 8 gives us:
Now I could have factored some 8's out of 25. There are actually three 8's in 25 with a remainder of 1.
We have shown that there is integer .
The integer I found that is n is 8km+5k+5m+3.
Therefore .

1) Parallelogram
2) Square
3) Rectangle
4) Trapezium or Trapezoid
Step-by-step explanation:
Step 1:
In a parallelogram the opposite sides will be parallel and equal
Square has all sides to be equal and the angles to be right angled.
In a rectangle, the four angles should be right angled and opposite sides should be equal.
A trapezoid or trapezium is a figure in which any of the pair of opposite sides should be parallel.
Step 2 :
1) This figure has opposite sides to be parallel and equal. Hence based on the first definition above, this is a parallelogram
Step 3 :
2) The second figure has opposite sides to be equal and the angles are of 90 degrees or right angled. Hence this is a square based on the second definition given in step 1
Step 4 :
3) The third figure has opposite sides to be equal and the angles are of 90 degrees or right angled. Hence this is a rectangle as per the 3 rd definition given in step 1
Step 5:
4 ) This figure has the horizontal pair of opposite sides to be parallel. Hence using the 4 Th definition in step 1, we can identify this as a trapezoid or trapezium.
