Answer plzzz I don’t understand

Step-by-step explanation:

in a triangle, the sum of all angles is 180 (angle sum theorem). so use the equation 180=50+80+10x. then solve

1. combine like terms

it becomes 180=130+10x

2. subtract 130 from both sides

it becomes 50=10x

3. divide both sides by 10

it becomes 5=x

so, x=5

hope this helped :)

median is the value separating the higher half of a data sample, a population or probablity distribution from the lower half.

step-by-step explanation:

say you have 3,8,7,3,1,9,8 order them from lowest to highest

if orderd it would be 1,3,3,7,8,8,9 now you take away from the lowest and the highest until you end up in the middle.

so you would remove the 1 and 9 leaving you with 5 digits remaining

when you've reached the middle that would be your answer so in this case the answer is 7

if there were two numbers left say 7 and 5 you'd and them together so 12 then divide by 2 witch would equal 6 so the answer would be 6

good luck on that project hoped i you at all

yes the total will be same because in both of them the expression.is rearranged but their sign remains the same hence it hss just been shuffled
