Answer:
C. 74º
Step-by-step explanation:
k equals to 106º
take 180º and subtract 106º
=74º
c. 74
We know that the two lines are parallel, therefore Angle N and Angle F are equivalent as they are corresponding angles. We can first find Angle F to find Angle N.
Angle F + 106 = 180 (Linear pair/supplementary angles)
Angle F = 74
Angle N = Angle F
Angle N = 74

hi,
you have then : 2100 * 1.045 ^n = 47 200
1.045^n = 47200 /2100
1.045^n = 472/21
n = ln ( 472/21 ) / ln ( 1.045)
n ≈71 years
let's check : 2100 *1.045^70 = 45746,68 and 2100 *1.045^71 = 47805.28
