Answer:9
Step-by-step explanation:
Use the pythagorean theorem. 
We know both a and c, so it becomes
=
16+b^2=97=
97-16=b^2=
81=b^2=
9=b
Answer:
45% of 40 is 18% of <em>100</em>
Step-by-step explanation:
Let 45% of 40 = 18% of <em>x</em>
.
Taking LHS (Left Hand Side):
45% of 40

Taking RHS(Right Hand Side):
18% of x

Equating (1) and (2):

Hence, 45% of 40 is 18% of <em>100.</em>
Answer:
X-8
Step-by-step explanation:
Thats it.
Answer:
12 units
Step-by-step explanation:
From the given figure, it can be seen that AB=BC, thus
From ΔBEC, using the Pythagoras theorem, we have





Now, from ΔABE, using the Pythagoras theorem, we have




Thus, the measure of AE is 12 units.
The number are going like this,
*9 then +2
so the next few number will be:
45,54,56,65,67 etc.
