Answer: you can approximate any variable in math by looking at the variables in the equation and working the problem through ur head or in paper
Step-by-step explanation:
Answer:
u transpose all the constans to one side of the '=' sign and solve
Step-by-step explanation:
for example,
in the first question
the sides of the triangles are proportional then,
25/30 = x/ 10
=> (25x10)/30 = x
=> 250/30 = x
=> 8.33
im pretty sure like this u can do the rest, ;)
You can simplify the given expression by taking out those factors who are perfect squares.
The simplified form of the given expression will be 
<h3>How to simplify values which are under the root?</h3>
If possible, try to defactor what is inside the root.
For example, if 8 is under square root, then you can defactor 8 as made up of 2 times 2 times 2. Since 2 times 2 is perfect square, thus this can come out of the root.
Simply, some more such methods can be used to simplify these type of values.
<h3>Using the simplification method on given expression</h3>

Thus, after getting simplified, the expression becomes
