Answer:
115°
Step-by-step explanation:
1. Calculate the value of x

2. Calculate m∠NFE
m∠NFE = 14x + 3 = 14(8) + 3 = 112 + 3 = 115
Answer:$168.00
With original price $240 and 30% discount,
Price after discount:<u> $168.00</u>
You saved: $72.00
Answer:
You can plug in the simple interest formula A=P(1+rt) to get the amount is equal to 3500 (the principal in this case) times 1+ 3.49/100(10). This is 3500(1.349), and this is $4721.5.
X^2 + y^2 - 2x + 8y - 47 = 0
x^2 + y^2 - 2x + 8y = 47
(x^2 - 2x) + (y^2 + 8y) = 47
(x^2 - 2(1)x) + (y^2 + 2(4)y) = 47
(x^2 - 2(1)x + 1^2) + (y^2 + 2(4)y + 4^2) = 47 + 1^2 + 4^2
(x - 1)^2 + (y + 4)^2 = 64 = 8^2
