The length of the shadow is 124.7 in

<u>Explanation:</u>

<u />

Given:

Angle, θ = 30°

Height of the fence, h = 72 in

Length of the shadow, l = ?

Given:

tan 30° = $\frac{perpendicular}{base} = \frac{height of the fence}{length of the shadow}$

$\frac{1}{\sqrt{3} } = \frac{72}{l} \\\\l = 72\sqrt{3} \\\\l = 124.7 in$

Therefore, the length of the shadow is 124.7 in

That's false.
Let's see an instance:
10% of 300=30
20% of 100=20
It doesn't work here so it's false

Answer:

x = a³b + b²/ab + 1

Step-by-step explanation:

x = a² + b²/ab + 1

x = a² × (ab + 1) + b²/ab + 1

x = a³b + a² + b²/ab + 1

x = a³b + b²/ab + 1
