Which of the following is equivalent to the formula =c2+c3+c4+c7?
=sum(c2: c7)
=sum(c2,c4: c7)
=sum(c2, c3, c4: c7)
=sum(c2: c4, c7)

=SUM(C2:C4, C7)

Step-by-step explanation:

In excel 'C' represent the cell ( intersection of row and column ),

Also, '=sum( )' represents the function of addition in the excel,

Also, when we operate all consecutive cells from to

Then under the function formula we write

And, when we operate a cell with non consecutive cell

Then under the function formula we write

Hence, C2+C3+C4+C7 can be written as,

=SUM(C2:C4, C7)

just needed some points but try socratic

12

step-by-step explanation:

a triangle's   full angle is 180 degrees so 180 - 156 = 24. 24/2=12
