Question

Yao Ming is 7 feet and 6 inches tall and casts a shadow of 5 feet at one point during the day. The tree beside him is casting a shadow of 15 feet. How tall is the tree

Answer 1

Answer:

$l_2=9.87ft$

Step-by-step explanation:

From the question we are told that:

Yao Ming's Height $h_1=7.6ft$

Length of Yao Ming's shadow $l_1=5feet$

Tree Height $h_2=15ft$

Generally the equation for Tree Shadow $l_2$ is mathematically given by

Since Shadow is cast by sun at same angle

 $l_2=\frac{h_2*l_1}{h_1}$

 $l_2=\frac{15*5}{7.6}$

 $l_2=9.87ft$
