Answer:
x = 20
Step-by-step explanation:
This is a 30-60-90° triangle, so the side length measurements will follow the rule of 1, √3 , 2.
You are solving for the hypotenuse (2), and you are given the side (1). Multiply it by 2:
10 x 2 = 20
x = 20.
If you need to solve for the third side, it is the same. Multiply this time by √3:
10 x √3 = 10√3.

Answer:69.92
Step-by-step explanation:
So since both of these lines are solid lines and not dashed, that means that the inequalities will have either ≤ or ≥.
Starting with the vertical line, since every point on that line is (0,y), this means that this line is x_0. And since the shaded region on this line is to the left of this line, this means that this inequality is x ≤ 0.
Now with this next line, I'll be forming it using the slope-intercept form (y = mx+b, m = slope and b = y-intercept). From looking at the graph, we can tell that the y-intercept is (-5,0). To find the slope, the equation is . For this, the two points I'll be using are (-4,-8) and (8,1).
Our equation will look and be solved like this:
And since the region shaded is below the line, ≤ symbol will be used with our inequality.
Using the information above, our inequality is y ≤ 3/4x - 5.
In short, the system of inequalities is x ≤ 0 and y ≤ 3/4x - 5.
Recall the double angle identity:
With measuring between 0º and 90º, we know . So from the Pythagorean identity, we get
Then
