Answer:

The height of tower is 322.7 feet.

Step-by-step explanation:

Given

Distance between a building and tower= 250 feet

BCDE is a rectangle .Therefore, we have BC=ED and CD=BE=250 feet

In triangle ABE

$tan\theta=\frac{perpendicula \; side }{hypotenuse}$

$\theta=38^{\circ}$

$tan38^{\circ}=\frac{AB}{BE}$

$\frac{AB}{250}=0.781$

$AB=0.781\times250$

AB=195.25 feet

In triangle EDC

$\theta=27^{\circ}$

$tan27^{\circ}=\frac{ED}{CD}$

$\frac{ED}{250}=0.509$

$ED=250\times0.509$

ED=127.25 feet

ED=BC=127.25 feet

The height of tower=AB+BC

The height of tower=195.25+127.25=322.5 feet

I believe 5 is 3 inches per year because 57 minus 40 and 1/2 is 16 and 1/2, so you divide 16 and 1/2 by 5 and 1/2 which equals 3, so 3 inches per year
