Answer:
We can only infer that OA=OB=PD=DE.
Step-by-step explanation:
Since, if two circles are congruent then their radius must be equal.
And, here A and B are the points in the circumference of circle O therefore, the distance of these points from the center O of the circle is the radius of the circle.
So, OA=OB. ( if we join the points O and C then OA=OB=OC)
Similarly, In Circle P, PE= PD. ( if we join the points P and CF then PD=PE=PF).

It is easy after using formula of t<span>he complex numbers
</span>z1= 5(cos25Deg + i sin25Deg)
z2= 2(cos80Deg + isin80Deg)
so z1/z2 =5/2cis(25Deg-80Deg)=5/2cis(-55Deg)
but we know that sin(-55Deg)= - sin(55Deg), and cos(-55Deg)=cos(55Deg),
finally the answer is Z=5/2(cos55Deg-i sin55Deg) (Z=z1/z2)
Answer: 57.5
Step-by-step explanation: The first thing you need to know about the order of operations is that multiplication and division come before addition and subtraction.
So in this problem, we are going to divide before we add.
Since 30 divided by 4 is 7.5, our next step will read 50 + 7.5 and 50 + 7.5 simplifies to 14.
That would be 8 + 2m^3. Think about this. Does it make sense to you?
