Question

Find the value of the variable.​

Answer 1

28

Explanation:

So for this problem, you need to use the midsegment formula. The midsegment formula is
`SG = (1)/(2) (b_(1) + b_(2))`. In this case,
`b_(1)` is 21 and
`b_(2)` 35.

Adding these together get 56. The next part of the formula is dividing by two, so
`(56)/(2) = 28` so you answer is x=28
