Sum of the interior angles of a pentagon is 720 degrees. Sum of two angles that form a bisected line is 180 degrees. So interior angles going clockwise are 138 degrees. 128 degrees. 119 degrees. 180- 2*t degrees. And 180 - 3*t degrees. So sum of angles is:
138+128+119+(180 - 2*t) + (180 - 3*t) = 720
25 = 5*t
t = 5 degrees.

Answer:</h2>
or 6.67%
<h2>
Step-by-step explanation:</h2>
In practice, the relative frequency of an event happening is the same as the probability that that event happened. In other words, the terms "relative frequency" and "probability" can be used interchangeably.
Now, the probability P(A) of an event A happening is given by;
P(A) =
From the question;
The event A is the situation of local residents having a post office box. Therefore the;
number-of-outcomes-in-the-event-A = 8 [since only 8 of the local residents have a post office box]
number-of-outcomes-in-the-sample-space = 120 [since there are altogether 120 local residents]
Therefore,
P(A) =
P(A) =
The relative frequency that a local resident does not have a post office box for receiving a mail is therefore,
PS: <em>Sometimes it is much more convenient to express relative frequencies as percentage. Therefore, the result above expressed in percentage gives:</em>
% = 6.67%
Answer:
the reason is they are equal to each other because they are both right angle triangle
An inverse operation is when after you add, you subtract. Same with multiplication and division.
