Answer:

b = 69/2 mm

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
