Step-by-step explanation:
Using the midline theorem
A segment joining the midpoints of 2 sides of a triangle ia
Parallel to the third side and half the length of the third side, thus
7x - 1 = 24 ( add 1 to both sides )
7x = 25 ( divide both sides by 7 )
x = 
Step-by-step explanation:
Number of areangements = 10C4
= 10 * 9 * 8 * 7 / (1 * 2 * 3 * 4) = 210.
