Step-by-step explanation:
Each number increases by 3. Therefore, n+3.
1. √169 = √(13 · 13) = 13
2. √169 = √(13 · 13) = 13
3. √81 = √(9 · 9) = 9
4. √225 = √(15 · 15) = 15
5. √196 = √(14 · 14) = 14

CPU means Central Processing Unit
There are 3 angles, the measure of angle 1 is 55.2° and etc, you want the angles to add up to 180° i think
55.2+34.7= 89.9
180-89.9= 90.1
x=90.1
