If the whole line is JL, then JK+KL=JL
JK:5x+8
KL:4x+4
5x+8+4x+4=84
Get all like terms on one side
5x+8+4x+4=84
-8 -4
5x+4x= 72
9x=72
x=8
Plug it into the equation
5(8)+ 8= 48
4(8)+4= 36
———————
84
So x=8
JK=48
KL=36

A quadratic equation is set up in the form of ax² + bx +c
First set equation = to 0
0= x² - 5x - 24
Next plug into quadratic formula( -b Plus or minus the √b²-4ac) ÷ 2a
[10 plus or minus √(25² - 4×1×24)] ÷ 2
Solve for inner parenthesis first 
√625- 96   = √529
Now set up two equations
(10 + √529) ÷2   = x   = 16.5
(10 -  √529) ÷2   = x   = -6.5 
So therefore x = 16.5 and -6.5

In triangle NOP p equals 600 inches angle P equals 96° and angle N equals 64° what is the area of triangle NOP to the nearest 10
DochEvi [55]

9514 1404 393

Answer:

  55,637.8 square inches

Step-by-step explanation:

We can find side n using the Law of Sines:

  n/sin(N) = p/sin(P)

  n = p(sin(N)/sin(P)) = 600·sin(64°)/sin(96°)

  n ≈ 542.246913 . . . . inches

The angle O is ...

  O = 180° -N -P = 180° -64° -96° = 20°

Then the area is ...

  A = 1/2·np·sin(O)

  A = (1/2)(542.246913 in)(600 in)·sin(20°) ≈ 55,637.81008 in²

The area of ∆NOP is about 55,637.8 in².
