$\bf -2x-4\le -4x+4\implies -2x\underline{+4x}-4 \le -4x\underline{+4x}+4
\\\\\\
2x-4\le 4\implies 2x-4\underline{+4}\le 4\underline{+4}\implies 2x\le 8
\\\\\\
x\le \cfrac{8}{2}\implies x\le 4$

Alekssandra [29.7K]

Answer:

sin-¹(10/11)

Step-by-step explanation:

The height of the building is 100 ft and the ladder is 110ft long .We can imagine this situation as a right angled ∆. For figure refer to the attachment .

We can use ratio sine here. Let the angle of elevation be theta.

In ∆ ABC :-

=> sinθ = p/h

=> sinθ = 100ft / 110 ft

=> sinθ = 10/11

=> θ = sin -¹ ( 10/11) .

<h3>Hence the angle of elevation is sin -¹ ( 10/11). </h3>
