14 + 2y - 3+ 7x - 12y +3x - 20=
Trava [24]

Answer:

The answer is 10x - 10y - 9

Step-by-step explanation:

14 - 3 - 20 = -9

2y - 12y = -10y

7x + 3x = 10x

14 + 2y - 3 + 7x - 12y + 3x - 20 = 10x - 10y - 9

Help Please ( and leave on how you solved it ) ":(<br> view pic below
Anton [14]

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
