Answer: ↓↓↓
Step-by-step explanation:
1. 13 < x < 21
2. 28 < x < 76
3. 24 < x < 42
4. 1 < x < 33
To find the number behind the x, just find the difference between the two numbers but make sure it's positive. Finding the number in front of the x, you add the two numbers together. X has to be greater than the smaller number but less than the greater number because to make a triangle, if two sides are added, their sum should be greater than the third side.
Hope that helped!

Explanation:
The car travel 10ft north then 15ft due west. In order to find the distance from starting point. We need to find the hypotenuse where the distance to north and west are the adjacent side.
We can use Pythagorean’s theorem according to that:
Let c be the distance from starting point.
And a and b be the distance travel to north and west.
a^2 + b^2 = c^2
10^2 + 15^2 = c^2
100 + 225 = c^2
325 = c^2
Sqrt(325) = c
5sqrt(13) = c
Therefore, the distance from starting point is 5sqrt(13) ft
Answer:
It is True 200% legit!
Step-by-step explanation:
Recall the double/half angle formulas:
We're given 
, and since 
is between π/2 and π, we expect 
to be negative. So from the Pythagorean identity, we find
Also, we know 
will fall between π/4 and π/2, so both 
and 
will be positive. Then we find
and it follows that
