Answer:
20ft.
Step-by-step explanation:
Sine = Opposite / Hypothenuse
Opposite = Height = 10ft
Hypothenuse = Length of ladder
Therefore, sin30° = 10ft / Length = 1/2
Length = 20ft
From triangle AED we can find the length of a side of ABCD
AD=(4^2+4^2)^(1/2) (pythagorean theoerem)
AD=32^(1/2)
For similar reasons as applied to the triangle AC=(2AD^2)^(1/2)
AC=(2*32)^(1/2)
AC=64^(1/2)
AC=8
Step-by-step explanation:
p=2(l+w)
30cm=2(n+6+n)
30cm\2=2n+6
15cm-6=2n
9cm=2n
n=4.5cm or w=4.5cm
l=w+6
l=4.5cm+6
l=10.5cm
