Answer:
Answer:
2x^4(10x+9)
Step-by-step explanation:
20x5+18x4
20x5+18x4
=2x4(10x+9)
2x^4(10x+9)
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
