Step-by-step explanation:
||x-5|+2|≤3
-3 ≤ (|x-5| +2) ≤ 3
-5 ≤ |x-5| ≤ 1
|x-5| ≥ -5 => not required
|x-5| ≤ 1
-1 ≤ x-5 ≤ 1
4 ≤ x ≤ 6
the Solutions:
{4≤ x ≤ 6}
Answer: 8√2
Explanation: Use the 45-45-90 theorem to solve.

Answer:
27
Step-by-step explanation:
Let x be the number,
2x - 6 = 48
2x = 48 + 6
2x = 54
x = 27

Answer:
87°
Step-by-step explanation:
The two marked angles are "vertical angles," so have the same measure. We can't read the number, but suspect it might be 87°. If so, then x° = 87°.
