Sam is framing a closet under a stairway. The stairway is 17 ft 3 in. long, and its angle of elevation is 31degrees. Find the depth of the closet to the nearest inch.

the depth of the closet is 105.1 inches.

Step-by-step explanation:

A right angle triangle is formed by the length of the stairway, its angle of elevation and the depth of the closet.

The length of the stairway represents the hypotenuse side of the right angle triangle. The depth, d of the closet represents the opposite side of the right angle triangle.

0.0833 feet = 1 inch

17 feet = 17/0.0833 = 204.1 inches

To determine d, we would apply

the Sine trigonometric ratio.

Sin θ, = opposite side/hypotenuse. Therefore,

Sin 31 = d/204.1

d = 204.1Sin31 = 204.1 × 0.515

d = 105.1 inches

30 units^2

step-by-step explanation:

area is l × w

the length is 3

and the width is 10

3 × 10= 30 units squared

the answer would be d

straight away you can eliminate a and c because not all books contain a scientific skill because some may be fiction. c is also wrong because it saids that the only way children can learn is through books which is incorrect.

b is also wrong because reading can be a scientific skill but not always, therefore it is wrong which leaves you with d, the correct answer since it said that it can children learn.

hope this ! : 3
