Answer:
225 m
Step-by-step explanation:
Since we know they are similar triangles
8 15
---------- = -----------
120 bridge
Using cross products
8 * bridge = 15* 120
8* bridge = 1800
Divide each side by 8
8/8* bridge = 1800/8
bridge = 225
225m
the 2 triangles shown are similar by AAA
so their sides are in the same ratio
bridge/15 = 120/8
bridge length = 15*15 = 225m
