Answer:
30.) B
I wasn't able to figure 29 out as some of the tables are cut off.
Hope this helps you out!
Step-by-step explanation:
There are 13 numbers here:
30, 30, 31, 32, 42, 49, 58, 58, 67, 67, 69, 78, 90.
The median number is the 7th number, which is 58.
x=9
The triangle is equilateral which means the sides are equal.
x+9 = 2x
Subtract x from each side
x+9-x = 2x-x
9 =x
