Answer 1

The value of x = 10.

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`

`(8x)/(8)=(80)/(8)`

`x=10`

Therefore, the value of x = 10
