Answer:
<h2>x = 117°</h2>Step-by-step explanation:
We know:
The sum of the quadrilateral angles measures 360°.
Therefore we have the equation:
The sum of angles x and D is equal to 360°. Therefore we have the other equation:
From (1) and (2) we have:
Answer:
The probability of spinning red is , the probability of spinning a 1 is
, the probability of spinning an odd number is
, and the probability of spinning a 9 is 0.
Step-by-step explanation:
Since there are a total of 6 possible outcomes, you can use this in the following questions. There are 2 red tiles, so the probability of spinning red is or
. Since there are only one 1 tile, the probability of spinning a 1 is
. Since there are three odd numbers, the probability of spinning an odd number is
. Since there are no 9 in the spinner, the probability of spinning a 9 is 0 or never.
