Answer:
Step-by-step explanation:
Triangle BCD is a right angle triangle.
From the given right angle triangle
BC represents the hypotenuse of the right angle triangle.
Taking 45 degrees as the reference angle,
BC represents the adjacent side of the right angle triangle.
BD represents the opposite side of the right angle triangle.
To determine BC, we would apply trigonometric ratio
Cos θ = adjacent side/hypotenuse side. Therefore,
Cos 45 = BC/2√2
√2/2 = BC/2√2
BC = 2√2 × √2/2
BC = 2
You cant you have to measure the angels and then you write down what you get after measuring.
Answer:
13.5 glasses of water
Step-by-step explanation:
If:
1 water glass can hold 2/9 of a litre
x water glasses can hold 3 litres.
Therefore, expressing it as a litre to glass ratio, we have::

Therefore, 13.5 glasses of water can be filled with a 3 litre bottle.
We're looking for the volume, since it's trying to find out the cost for filling the entire box.
We have our length, width, and height.
8, 6, and 1.
We're multiplying 8, 6 1, and 0.3 since it is $0.3 per sq ft,
Our equation is:
0.3 (8x6x1) = x
8 x 6 x 1 = 48.
48 x 0.3 is 14.4
$14.4 is your answer
Hope this helps!
