Evaluate and simplify tan 15º.

dimulka [17.4K]

Tan(15) = tan(45 - 30)

= [tan(45) - tan(30) ] / [ 1 + tan(30)tan(45)]

= (1 - 1/sqrt(3)) /(1 + 1/sqrt(3))

= (sqrt(3) - 1)/(sqrt(3) + 1)

= (sqrt(3) - 1)^2 /(3 - 1)

= 1/2 [3 + 1 - 2sqrt(3) ]

= (2 - sqrt(3) )

= 0.27 is your answer

A fire department's ladder is 110 feet long. A firefighter is trying to reach the top of a 100 foot building by leaning the ladd

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>
