Let's call the angle x.
The complement of the angle is 90 - x.
The supplement of the angle is 180 - x.
According to the problem, the supplement is six times as large as the complement:
180 - x = 6(90 - x)
Simplifying this equation:
180 - x = 540 - 6x
5x = 360
x = 72
Therefore, the angle is 72 degrees, which is answer choice B.

To construct a triangle, the sum of the lengths of any two sides must be greater than the length of the third side.
Let's check each set of line segments:
A. 7 cm, 4 cm, and 1 cm.
7 + 4 = 11, which is greater than 1.
7 + 1 = 8, which is also greater than 4.
But 4 + 1 = 5, which is NOT greater than 7.
Therefore, this set of line segments cannot be used to construct a triangle.
B. 8 cm, 3 cm, and 6 cm.
8 + 3 = 11, which is greater than 6.
8 + 6 = 14, which is greater than 3.
6 + 3 = 9, which is also greater than 8.
Therefore, this set of line segments can be used to construct a triangle.
C. 6 cm, 3 cm, and 2 cm.
6 + 3 = 9, which is greater than 2.
6 + 2 = 8, which is greater than 3.
3 + 2 = 5, which is NOT greater than 6.
Therefore, this set of line segments cannot be used to construct a triangle.
D. 9 cm, 2 cm, and 6 cm.
9 + 2 = 11, which is greater than 6.
9 + 6 = 15, which is greater than 2.
6 + 2 = 8, which is NOT greater than 9.
Therefore, this set of line segments cannot be used to construct a triangle.

On a number line, what is the distance between −17 and 9?
Bot
To find the distance between -17 and 9 on a number line, we need to calculate the absolute value of the difference between the two numbers:
|(-17) - 9| = |-26| = 26
Therefore, the distance between -17 and 9 on a number line is 26 units.
|(-17) - 9| = |-26| = 26
Therefore, the distance between -17 and 9 on a number line is 26 units.
