Question 1118503
<br>
The other tutor did not interpret the given information correctly.  The 128 feet is between the person and the flagpole -- not between the flagpole and the end of the person's shadow.<br>
From the end of the person's shadow to the person is 32 feet.
From the end of the person's shadow to the base of the flagpole is 32+128 = 160 feet.
From the end of the person's shadow to the base of the tree is 32+128+800 = 960 feet.<br>
(a) To find the height of the flagpole:
{{{6/32 = x/160}}}
{{{x = 160*6/32 = 5*6 = 30}}}<br>
The height of the flagpole is 30 feet.<br>
(b) To find the height of the tree:
{{{6/32 = x/960}}}
{{{x = 960*6/32 = 6*30 = 180}}}<br>
The height of the tree is 180 feet.
