Answer:

The value of x = 10.

Step-by-step explanation:

From the given triangle,

The value of angle M = (3x + 28)°

The value of angle K = (5x - 18)°

The value of angle L = 90°

We know that the sum of a triangle is 180°.

i.e.

K + L + M = 180°

(5x - 18)° + 90° + (3x + 28)° = 180°

$5x-18+90+3x+28=180$

$5x+3x-18+90+28=180$

$8x-18+90+28=180$

$8x+100=180$

$8x=80$

$\frac{8x}{8}=\frac{80}{8}$

$x=10$

Therefore, the value of x = 10
