Answer:
It's a isosceles triangle, i am not saying its clearly implied in the diagram with the red lines.... Which state that both the sides have same length
Hence if on ne side makes 55 with the base therefore the side with same length will make 55 with the base too
Hence its
55+55+x=180
X= 180-55-55
X= 70 degree
Therefore x is 70 degree
1. opposite sides are equivalent , opposite angles are equivalent
2. 4 sides, 4 angles, both answers for number one also work
3. A square
Answer:3000m and 3km
Step-by-step explanation:
To convert from cm to m,divide by 100 and from m to km,divide by 1000
<span>Answer:
The multiplication factor of increase should be inverse of the multiplication factor of decrease.
e.g. Say you have a number 100.
You increase it by 25%. The multiplication factor is 5/4 i.e. when you multiply 100 by 5/4, you get 100*5/4 = 125. This is 25% more than 100.
Now you want to decrease it by a certain % such that you get 100 back.
Basically, 100*5/4 * x = 100
So x = 4/5 (inverse of 5/4)
Hence, you decrease by 20% (the multiplication factor of 20% is 4/5)
or
Use this formula: cumulative % change = a + b + ab/100
You want the cumulative change to be 0.
a + b + ab/100 = 0
If you know that you are increasing by 25% and want to find the % by which you should decrease to get the same number,
25 + b + 25b/100 = 0
5b/4 = -25
b = -20
So you need to decrease (hence you get the -ve sign) by 20%.</span>
I’m not sure that question.... sorry
