Answer: 2
Step-by-step explanation: These are similar trapezoids so you take 4 * 5 /10 = 2
Answer:
the slide it's self is 10 feet long
Step-by-step explanation:
it says the height is 8ft off the ground which means that the slide being at a 45 degree angle it has to be at least 2 ft taller than the ladder
Answer: 5.6ft²
Step-by-step explanation:
Area of a rectangle = length x width
=
(7ft)
= 
= 5.6ft²
If you take a look at my really poorly drawn diagram, we can see it is a trigonometry problem. The angle, however, is outside the triangle, and we can find the angle inside the triangle next to it by taking it away from 90°:
90°0' - 72°54' = 17°6' ≈ 17.1°.
We can find the other angles becuase one is 90° and the other is:
180°-90°-17°6'=72°54' ≈ 72.9°(which you can see if you know your angle theorems).
We now have diagram 2, nicely simplified so we can see where to go.
Using the Sine Rule, i.e.

We can rearrange to find our length b:

Substituting numbers in:

b=366 feet.
