Help with trig homework

Answer 1

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

Answer 2

Answer:

225m

Step-by-step explanation:

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
