sp2606 [1]

Answer:

$b.\ cos 70 =\dfrac{4}x$ is the correct answer.

Step-by-step explanation:

First of all, let us label the diagram as shown in the attached figure.

OR = 20'

QS = 16'

$\triangle OPQ$ is the right angled triangle that we get.

$\angle P=90^\circ$

$\angle O =70^\circ$

From the given figure symmetry, we can clearly see that:

Side OP = OR - QS

OP = 20 - 16 = 4'

Now, let us use trigonometric identity of cosine in $\triangle OPQ$ .

$cos\theta = \dfrac{Base}{Hypotenuse}$

$cosO= \dfrac{OP}{OQ}\\\Rightarrow cos70^\circ= \dfrac{4}{OQ}$

Let the distance of ramp, OQ = x'

So, the above ratio becomes:

$cos70^\circ= \dfrac{4}{x}$

So, the correct answer is:

$b.\ cos 70 =\dfrac{4}x$

How would i find AB?

Alina [70]

<h3>Answer: 25.9</h3>

========================================

x = length of AB

The parallel bases of the trapezoid can be added up, and divided over 2, to get the length of the midsegment. The midsegment is the line that cuts the nonparallel sides (or legs) of the trapezoid in half. The midsegment is parallel to the bases.

So,

(AB+DC)/2 = MN

(x+11.5)/2 = 18.7

x+11.5 = 2*18.7

x+11.5 = 37.4

x= 37.4-11.5

x = 25.9

AB = 25.9
