N=S(P-V)-F. Solve for the S

Step-by-step explanation:

The given equation is :

N=S(P-V)-F ...(1)

We need to solve the above equation for S.

Adding F both sides in equation (1)

N+F=S(P-V)-F+F

N+F=S(P-V)

Dividing both sides by (P-V). So,

So, the above is the expression for S.

Triangle A:

Scalene

Triangle B:

Isosceles

Triangle C:

Equilateral

Triangle D:

Isosceles

Step-by-step explanation:

Scalene = No sides are the same length

Isosceles = 2 sides are the same length (only 2)

Equilateral = All sides are the same length
