Angle B = 68 degrees
Using the Law of Sines
b / sin(B) = c / sin (C)
b = sin (68) * c / sin (49)
b = 0.92718 * 3 / 0.75471

Answer:

b=4

Step-by-step explanation:

Let us draw a triangle ABC, with A = 63°, C = 49°, and c = 3.

In the triangle ABC,

A +B +C = 180°

63°+B+49°= 180°

B = 180°-63°-49°

B = 68°

Use Sine law to find b

\frac{c}{sin C}=\frac{b}{\sin B}\\\\\frac{3}{\sin49}=\frac{b}{\sin68}\\\\b=\frac{3\sin68}{sin49}\\\\b=3.7

In the nearest whole number b = 4

Solve 5x + 14 = k for x. A. B. x = k – 14 C. x = 5k – 14 D.
wariber [46]
4x + 14 = k

Do the opposite of PEMDAS
Isolate the x, subtract 14 from both sides
4x + 14 (-14) = k (-14)

4x = k - 14
divide 4 from both sides
4x/4 = (k-14)/4

x = (k-14)/4 is your answer

hope this helps

Look at picture, answer quick please
Tpy6a [65]

Step-by-step explanation:

1. C = the graphing is slowly increasing, then he walks across the top so it is flat

2. D = it started out slow and gradually got higher, which is what the story said

3. H = he had to stop walking, and there is a part of no movement in the graph H

Westkost [7]

rule is to  shift 8 units left & , shift 2 units down , Correct option C)  T<-8,-2> (Jessica) ,

<u>Step-by-step explanation:</u>

Here we have , Jessica was sitting in row 9, seat 3 at a soccer game when she discovered her ticket was for row 1, seat 1. We need to Write a rule to describe the translation needed to put her in the proper seat. Let's do this:

Suppose the above problem in coordinate system where we have a point P(9,3) , And we need to write rule for translation of this point to Q(1,1) .

Let , (x,y)=(9,3) , Now shift 8 units left i.e.

⇒  (x,y)=(9,3)

⇒  (x-8,y)=(9-8,3)

⇒  (x-8,y)=(1,3)

Now , shift 2 units down i.e.

⇒  (x-8,y)=(1,3)

⇒  (x-8,y-2)=(1,3-2)

⇒  (x-8,y-2)=(1,1)

Therefore , rule is to  shift 8 units left & , shift 2 units down , Correct option C)  T<-8,-2> (Jessica) ,
