For the mean, add together all of the numbers together (let's call the total x) and count how many numbers there are. (let's call this number y). divide x by y, and that is your mean. for the median, put all the numbers in order, and the median is the number in the middle. if there are two numbers in the middle, add them together and divide them by 2.
So the trapezoid has 2 parallel sides making segments AD and BC transversals
Therefore making angle c and angle b add up to 180
(180-3x) + 3x + 180-9x +9x
180 +12x = 360
180= 12x
x= 15
A I’m pretty sure. Hopefully that helps
Answer:
2 and 5/11
Step-by-step explanation:
first we find how many times 11 goes into 27. It goes in twice, which gives us our whole number, 2. Then we need to find the fraction part, which is whatever's left over. 27-22 is 5, giving us 2 and 5/11
