Answer:28.26

Step-by-step explanation:

Φ=180 since it's in a straight line

Radius=r=9

π=3.14

Length of arc=Φ/360 x 2 x π x r

Length of arc=180/360 x 2 x 3.14 x 9

Length of arc=0.5 x 2 x 3.14 x 9

Length of arc=28.26

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 = $\frac{25}{7}$
