๐ข The wait is over, MNHSians! Itโs finally time to reveal the answer to last weekโs "๐๐ผ๐๐ผ๐๐๐๐ ๐๐ผ ๐ฝ๐ผ?" challenge! ๐คฉ
Word Problem:
On a sunny day, a 4 meter tall light pole casts a 5 meter long shadow at the same time a nearby building casts a 15m long shadow.The sun rays strike both the building and the light pole at the same angle.
In this case find the height of the building.
Step by step solutions:
Using the triangle proportionality theorem
Length of building shadow: 15 meters
Height of the light pole: 4 meters
Length of light pole shadow: 5 meters
Let x be the building height
Building height/Building shadow. =. light pole height/Light pole shadow
X/15. = 4/5
Then cross multiply
5x = 60
Divide both side by 5
x = 12
So the building height is equal to 12 meters
Did you get it right? ๐ค
