The correct answer it is 18 perimeter
Answer:
α = 13.39249775
Step-by-step explanation:
Length of the vamp = 21 ft long
Height of the vamp= 5 ft
using SOHCAHTOA
tanα = opposite /adjacent
Tan α = 5/21
α = arctan(5/21)
α = 13.39249775
Answer:
YES IT IS A PERFECT SQUARE
Step-by-step explanation:
equate the equation to zero
x^2+8x+16=0
c is the product while the coefficient of b is the sum
P=16
S=8
find a pair of numbers that the product is 16 and the sum is 8
the numbers are (4,4)
(x^2+4x) (4X+16)
ignore 8x and arrange as shown above
then bracket the equation
x(x+4)+4(x+4)
you simplify and remain with (x+4) (x+4)
having similar roots making it a perfect square
Answer:
= 3.1
= 2.6
= 4.5
= 3.3
