Wdym by animal testing? Like doing experiments on rats as an example?
Answer:
Step-by-step explanation:
The idea here is to find the value for x and y, then add them together. See the pic I attached below. We will solve for side x first.
Side s is across from the reference angle of 48 degrees; side measuring 50 m is adjacent to the reference angle 48 degrees. Therefore, we will use the tangent ratio to solve for x:
and
50tan(48) = x so
x = 55.53m
Now we will do the same and solve for y. This time the reference angle is 28 degrees. Side y is opposite the reference angle and the side measuring 50 is adjacent to the reference angle, so we will use the tangent ratio again:
and
50tan(28) = y so
y = 26.59. Therefore,
x + y = 55.53 + 26.59 and
the height of the taller building is
82.1 m
He estimated to the tenths place. 336 is about 340. 289 is about 290. 340-390=50

Please check the explanation.
Step-by-step explanation:
Given the expression
3x-12
1)
Writing the expression in an equivalent form
3x-12
Factor out common term 3
3x-12 = 3(x-4)
Thus, 3(x-4) is equivalent to 3x-12.
2)
Writing the expression in an equivalent form
3x-12
Multiply the expression by 2/2
![3x-12\:=\frac{2}{2}\:\times \:\left[3x-12\right]](https://tex.z-dn.net/?f=3x-12%5C%3A%3D%5Cfrac%7B2%7D%7B2%7D%5C%3A%5Ctimes%20%5C%3A%5Cleft%5B3x-12%5Cright%5D)
Therefore,
is equivalent to 3x-12.
