Answer:
what is the subject and grade please tell
Step-by-step explanation:
The distance between -6 and -3 on a number line is 3.
Answer:
x = 20°
y = 30
Step-by-step explanation:
The triangle given on close inspection, it is an equilateral triangle.
Each angle in an equilateral triangle is equal. Likewise, each side is equal.
Thus;
16 + y = 46
y = 46 - 16
y = 30
The triangle that has angle 80°, the other complete angle is 60° because it's an angle of an equilateral triangle.
Thus, the smaller angle there is;
180 - (80 + 60) = 40°
Because sum of angles in a triangle is 180°
Now, x + 40 = 60°
Since that's also an angle of an equilateral triangle.
x = 60 - 40
x = 20°
When the sign is < or > (less than/greater than), you graph an open circle.
When the sign is ≤ or ≥ (less than/greater than <u>or equal to)</u>, you graph a closed circle.
The 4th option is your answer since the sign is ≥
