Answer:
U=32m
Explanation:
Big triangle
Little triangle
Compare lengths & find scale factor (s.f)
We've got base lengths, that's what we will use to find the scale factor.
27.3 ÷ 15.6 = 1.75 s.f
We're going from big triangle, to small; so, divided by 1.75s.f to find length of u
56 ÷ 1.75 = 32
U= 32m
Hope this helps!
