7 0

Answer:

D) 72°

Step-by-step explanation:

Sum of angles 7 and 8 is 180° as they are supplementary

Angles 7 and 3 are corresponding angles and they measure same as per property of corresponding angles, therefore:

m∠3 = m∠7
m∠7 = 180° - m∠8 = 180° - 108° = 72°
So m∠3 = 72°

Option D is correct

For the equation given below, evaluate y′ at the point (−2,2)<br> xe^y−4y=2x−4−2e^2

jeka94

Implicit differentiation
chain rule is important here

I'll show the steps partially
$e^y+xe^yy'-4y'=2$
$xe^yy'-4y'=2-e^y$
$y'(xe^y-4)=2-e^y$
$y'=\dfrac{2-e^y}{xe^y-4}$
now evaluate for (-2,2)
x=-2 and y=2
$y'=\dfrac{2-e^2}{-2e^2-4}$
$y'=\dfrac{2-e^2}{-2e^2-4}$
$y'=\dfrac{e^2-2}{2e^2+4}$
that's it, simplest form
