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

Answer:
You do this by using the Pythagorean Theorem.
Answer: x² + 2x - 15
Step-by-step explanation:
<u>Concept:</u>
When we encounter questions that ask us to simplify expressions that consist of multiple parentheses, it is suggested to use the FOIL method to ease the process.
<u>Solve:</u>
Given
(x - 3) (x + 5)
Expand parentheses
x² + 5x - 3x - 15
Combine like terms
x² + (5x - 3x) - 15
x² + 2x - 15
