Answer:
And then the rectangular coordinates for this case are :

Step-by-step explanation:
We have the following point given
and we want to conver from polar to rectangular coordinates and we need to use the following formulas:


For this case we have that:
And:

Replacing we got:
And then the rectangular coordinates for this case are :

Answer:
117
Step-by-step explanation:
180-101 = 79
180-(79+38)
180-117
63
180-63=117
Between two rational numbers there are an infinite number of irrational numbers.
Example:
The formula of a distance between two points:

We have the points P(2, 2) ans Q(7, 4). Substitute:

<h3>Answer: PQ = 5.4</h3>
