Since there is no specific situation or measurements for this, we just assume a circle with an arc BD. It has arbitrary values. In a circle, an arc can be measured by the measure of an arc. A measure of an arc is an angle that an arc makes at the center of a circle which it is a part. It has degrees units. It can be calculated when the length of an arc is given by using certain equations. The measure of an arc and the length of an arc always goes together.
Pythagorean theorem
the shadow legnth=bottom leg
legnth from top of tower to end of shadow=hypotounuse
height of tower=vertical leg
a^2+b^2=c^2
a and b are legs
c=hypotonuse
11^2+b^2=61^2
121+b^2=3721
minus 121 both sides
b^2=3600
sqrt both sides
b=60
height of toer is 60 feet
