We have two similar triangles, the one as a whole and the one inside of it. To calculate the height of the flagpole we can set up a proportion. First calculate the length of the base of the smaller triangle.
16.60 - 12.45 = 4.15m
The height is 1.65m, set up a proportion:
Cross multiply:
Divide 4.15 to both sides:
So the height of the flagpole is 6.6 meters tall.
16.60 - 12.45 = 4.15m
The height is 1.65m, set up a proportion:
Cross multiply:
Divide 4.15 to both sides:
So the height of the flagpole is 6.6 meters tall.
