Answer:
Step-by-step explanation:
m∠5 +m∠6 = 180° ( the angles form a line)
m∠2 + m∠3 = m∠6 ( exterior angle is the sum of 2 not adjacent angles)
m∠2+m∠3+m∠5= 180° (sum of angles in a triangle is 180°)
Use exp/log functions to rewrite y as

One of the properties of logarithms lets us bring down the exponent, so

Now take the derivative of both sides with respect to x. By the chain and quotient rules,

Simplify:

This would 70% of 80. To find this multiply (7/10) by 80 to get your answer: 56.
