Hey there,

Answer:

k(a + b) = ka + kb

2(3r + 7) - (2+ r)

= 2*3r + 2*7 - (2 + r)

= 6r + 14 - (2 + r)

= 6r + 14 - 2 - r

= 6r - r + 14 - 2

= 5r + 12

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 ;-)
