Answer:

b = 69/2 mm

Step-by-step explanation:

Let h:  height of triangle

Let b:  base length

Writing the height in terms of the base length:  h = 2b + 5 mm

We equate that to the given height:  74 mm = h = 2b + 5 mm.

Solving this for b, we subtract 5 mm from both sides, obtaining

69 mm = 2b.

Then b = 69/2 mm
