0.069
Step-by-step explanation:
0.576/8.3 = 0.06939759036
Answer:
a) 
b) Irrational
Step-by-step explanation:
a) Let 
Then 
Subtract (a) from (b)
b) From part a) 
is a rational number but 
is an irrational number.
But 
is not a rational number because the product of a rational number and an irrational number is an irrational number.
In the b section on this piece of paper, we can see, that this would practically be a pie graph, or if you would want to call it a graph in general. As the question stated, we see how we would want to find the perimeter of the figure. So this, sense this would only be 1/4 of the figure, we would then do 4(in) x's 4 and from this, your perimeter would give you 16(in).
Its very simple. Every triangle has a maximum degree of 180°.
We can substract all of the given angles to get our x angle, like so:
x = 180 -102 - 39 = 39°
