Estimate the height of a tree using the following measurements:height of the rod:180 cm,length of the shadow of the rod is 116 cm,length of the shadow of the tree:840 cm,calculate the height of the tree

1303.45 cm

Step-by-step explanation:

The triangles formed by a rod and its shadow and a tree and its shadow are similar triangles, so the ratios of their heights to the lengths of their shadows are equal.

Let x be the height of the tree. Setting the ratios equal, we get:

180/116 = x/840

Solve for x:

x = 840 * (180/116)

x ≈ 1303.45 cm

It's is $61 585 because all you have to do is mulitiply 356 by $80, 275 by $60 and 369 by $45
356 x 80 = 28 480 275 x 60 = 16 500
369 x 45 = 16 605
Add the answers together

28 480. And there's your answer
16 500
+16 605

$61585
