Answer:
38°
Step-by-step explanation:
The figure given is a triangle.
Sum of angles in triangle = 180°
So;
∠D + ∠E + ∠F = 180°
( 5x - 2) + (9x + 3) + (11x - 21) = 180
5x -2 + 9x + 3 + 11x -21 = 180
25x -20 = 180
25x = 200
x = 8
Now since ∠D = 5x -2;
∠D = 5(8) - 2 = 38°
C.) The independence of the two ice machines means that knowing how much one machine fills does not help us predict how much the other fills.
Answer:
The phrasing of the question is a bit weird maybe, I think, but it's one of the lobes in your brain, I suppose.
<span>Naming of rays
Rays are commonly named in two ways:
By two points.
In the figure at the top of the page, the ray would be called AB because starts at point A and passes through B on it's way to infinity. Recall that points are usually labelled with single upper-case (capital) letters. There is a symbol for this which looks like this: AB This is read as "ray AB". The arrow over the two letters indicates it is a ray, and the arrow direction indicates that A is the point where the ray starts.
By a single letter. (I have not seen this done.)
The ray above would be called simply "q". By convention, this is usually a single lower case (small) letter. This is normally used when the ray does not pass through another labeled point.</span>
Answer:
110 is not a perfect square.
