Answer:
61
Step-by-step explanation:
1. let the unknown be x
2. using theorem of Pythagoras that states the hypotenuse will be equal to the sum of the other two sides we can determine that 75=14+X
3. this implies that X=75-14
4. therefore X= 61
Given :
We know the identity
We use this property to simplify the left hand side
So
we know ,
when then
For
Add on both sides
Finally we add 2npi for general solution
So options C and D are correct
Make an equation for the problem. In the problem they are averaging the amounts between the two.
A joint relative frequency is found by dividing a frequency that is not in the Total row or the Total column by the frequency’s row total or column total.
