c.  40.

Step-by-step explanation:

Since the small and large triangles are similar we have the equation:

45 / 90 = 6x + 4 / 4x + 56

1 /2 = 6x + 4 / 4x + 56

2(6x + 4)  = 4x + 56

12x + 8 = 4x + 56

8x = 48

x = 6

So the length of the mid segment = 6(6) + 4 = 40.

1) c 2143.6 cm

2) c 113.0 m

3) a 33.5 ft

4)   d 2 cm

5) c 20 mm

6) 180 in

7) d 120 ft

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
