Answer:
x+2 < 11 and -x-2 < 11
Step-by-step explanation:
absolute value function has two solution
|x| = a
Then x=a and - x= a
|x + 2| < 11
Then x + 2 < 11 and -(x + 2) < 11
x + 2 < 11 and -x - 2 < 11
The answer is B. obtuse, because obtuse angles are between 90° and 180°. Acute angles are between 0 and 90, right angles are 90° exactly, and straight angles are 180°. I hope this helps!
Triangles ALWAYS measure 180 degrees.
78 + 23 = 101
180 - 101 = 79
The measure of the other angle is 79 degrees.
Hope this helped

Answer:
21
Step-by-step explanation:
8 * 2 = 16
5 * 2 = 10
68 - 16 = 52 - 10 = 42.
The perimeter of the square is 42.
42 / 4 = 10.5. 10.5 is the length of a side.
10.5 * 2 = 21.
