Answer:
24
Step-by-step explanation:
2*1+1+2*2+1+2*3+1+2*4+1=24
The answer of 
is √ 2
<u>Step-by-step explanation:</u>
The value of 
= √2/ 2
The value of 
= √2/ 2
= √2/ 2 + √2/ 2
= √2 + √2 / 2
= 2 √2 / 2
Dividing √2 by 1
= √2
=
Multiply both sides by 15
6 =
Multiply both sides by c
6c = 30 Divide both sides by 6
c = 5
