ET is tangent to circle A so ET is perpendicular to AT
So <ATE = 90°
Given <TNG = 35°
<NET = <ATE - <TNG
= 90° - 35°
= 55°
Answer is 55°

Answer:
B
Step-by-step explanation:
Price elasticity is defined as

.
Here, the question has omitted to define variables, so we will ASSUME
p=price
x=variable,
and we're given
p+x^2-160=0
We calculate

by implicit differentiation with respect to p:
1+2x (dx/dp)=0
=>
E(x)=(dx/dp)=-1/(2x)
Therefore the price elasticity at x=65 is
E(65)=1/(2*65) =-1/130 (approximately -0.00769)
