First we need to get x
<RNA = <ENV [v.o.a]
8x+12=5x+57
8x-5x=57-12
3x=45
x=15

<ENV= (5×15+57)
<ENV =132
the answer is D

Answer: The answer is (D) 132^\circ.

Step-by-step explanation: We are given a figure where the line segments AE and RV are intersecting at the point N. We are to find the measure of \angle ENV.

Also, given that

\angle ANR=(8x+12)^\circ,\\\\\angle ENV=(5x+57)^\circ.

Since the line segments AE and RV intersect at N, so we have

\angle ANR=\angleENV~[\textup{vertically opposite angles}]\\\\5x+57=8x+12\\\\\Rightarrow8x-5x=57-12\\\\\Rightarrow3x=45\\\\\Rightarrow x=15.

Therefore,

\angle ENV=(5\times 15+57)^\circ=(75+57)^\circ=132^\circ.

Thus, (D) is the correct option.

GalinKa [24]
The rule is add 1.05 because it's 1.8 first then it's 2.85 so you add 1.05 to 1.8 and you will get 2.85. Same with the other numbers.

PLEASE HELP ASAP, I WILL GIVE BRAINLESSLY ANSWER <br> SHOW WORK PLEASE
zhannawk [14.2K]

Answer:

C. N(t)=150\cdot 3^t

Step-by-step explanation:

You are given the exponential function n(t)=ab^t.

From the table, N(t)=150 at t=0, thus

N(0)=a\cdot b^0\\ \\150=a\cdot 1\ [\text{ because }b^0=1]

Also N(t)=450 at t=1, thus

N(1)=a\cdot b^1=a\cdot b.

Since  a=150, substitute it into the second equation

450=150\cdot b\\ \\b=\dfrac{450}{150}\\ \\b=3

and the expression for the exponential function is

N(t)=150\cdot 3^t

Find the remainder when f(x) is divided by (x - k) <br> f(x) = 5x4 + 8x3 + 4x2 - 5x + 67; k = 2
yan [13]

It is to be solved by reminder thorem
f(x)/(x-k) will have reminder f(k), 
so, f(2) = 5*(2^4) + 8 *(2^3) +4* (2^2) -5(2) +67

             =5*16 + 8*8 +4*4 -5*2 +67
             =80 + 64 + 16 -10 +67

             = 217
