Differentiating both sides of

with respect to
yields

At the point (3, 4) (so
and
), the tangent line has slope

Then the tangent line to (3, 4) has equation

Workers being paid on commission get paid based solely on their performance.
They get paid based on their performance and not their hours.
All the measures in a triangle are equal to 180 degrees.
Let the unknown angle= x.
40+89+x= 180
Combine like terms.
129+x= 180
Subtract 129 from both sides.
x= 51
The angle is equal to 51.
I hope this helps!
