Product rule:


Power rule:

The exponential function is its own derivative:

Assuming the base of
is
, its derivative is

But if you mean a logarithm of arbitrary base
, we have



So we end up with


w=37
2w+w+69= 180 knowing that all triangles add up to 180 form an equation
3w+69=180 combine like terms and subtract 69 from both sides
3w=111 divide by 3 from both sides
w=37
