<h2>Answer:</h2>

Hence, the angle of elevation of the ramp is:

                              30°

<h2>Step-by-step explanation:</h2>

Let θ be the angle of elevation that the ramp makes to the storeroom.

We model this problem with the help of a right angled triangle ΔABC the length of whose perpendicular side is 5 meters and the hypotenuse is 10 meters.

Hence, using the trignometric identity we have:

\sin \theta=\dfrac{AB}{AC}\\\\\\\sin \theta=\dfrac{5}{10}\\\\\\\sin \theta=\dfrac{1}{2}\\\\\\\theta=sin^{-1}(\dfrac{1}{2})\\\\\\\theta=\dfrac{\pi}{6}

      Hence, the angle of elevation is:

                  30°

The angle of elevation is 26.565 (3dp)
let h be the end height of the ramp above
the ground , l be the length of the ramp and
the angle of elevation is (30)
i'm not sure, sorry

6 ft.<br> 12 ft.<br> 8 ft.<br> The area of this irregular<br> figure is<br> -sq. ft.<br> 16 ft.
nikdorinn [45]

Answer:

When we know all 3 sides, we use Heron's Formula

area = sqrt [s *(s-a) * (s-b) * (s-c)]

where "s" is the semi-perimeter which in this case equals

s = (6 + 8 + 12) / 2   = 13

area = sqrt [13 * 5 * 7 * 1]

area = sqrt 455

area = 21.3307290077

area = 21.33 square feet (rounded)

Lexi is making an orange drink for party. She puts 4 pints of orange drink and 2 pints of water into a punch bowl. Her friend Ol
Nina [5.8K]
I think she can add 5p more of orange which is 9p and 6p more water which is 8p. I'm pretty sure this works because 9 is the next closest multiple of 3 and 8 is one number less than that. Hope this helps!

arsen [322]
2/5 is equivalent to 4/10 so at the end of February 4/10 was used up
And at the end of January, 3/10 was used
so 4/10 + 3/10 = 7/10

At the end of February, 7/10 of the wood was used
