Answer:
x = 20√2 and y = 20√3.
or x = 28.28 and y = 34.64 to the nearest hundredths.
Step-by-step explanation:
Take the 2 'inside' triangles. They are similar.
So we have x / (60-40) = 40 / x
x/ 20 = 40 /x
x^2 = 800
x = √800
x = 20√2
y = √(800 + 20^2)
= √(1200)
= 20√3.

Step-by-step explanation:
If the length of a bridge on a map is 1 cm,then the actual length = 40,000
If the length of a bridge on a map is 1.5 cm,then the actual length= 1.5 * 40000
= 60000.0 = 60,000 m
