What is mKNL?<br> Enter your answer in the box.

sergejj [24]

Answer:

102°

Step-by-step explanation:

As the vertically opposite angles are equal,

$5x+2={3(x+14)$

Now let's solve for x now

$5x+2=3(x+14)\\$

$5x+2=3x+42$

$5x-3x=42-2$

$2x=40$

$\frac{2x}{2} =\frac{40}{2}$

$x=20 \\$

Now let's find the value of KNL

$3(x+14)\\3(20+14)\\3*34\\102$

Hope this helps you.

Let me know if you have any other questions ;-)

-3/4 n + 1/8 n=1/2<br><br>PLEASE SHOW WORK

Nesterboy [21]

Answer:

n = -4/5

Step-by-step explanation:

-3/4 n + 1/8 n= 1/2

use the rules of signs for multiplication

-3/4 n + 1/8 n= 1/2

multiply both sides 8

-6n + n = 4

collect like terms

-5n = 4

divide both sides by -5

n=-4/5

or alternative form

n=-0.8
