D becaucause you have to do 12x8 and then 12x5 and whatever 12x8 is you but the answer bring down the + and do 12x5
The value of x is 30; hence 4x is equal to 120. That is because the sum of the angles of a triangle is 180. So, add x, x and 4x together, you get 6x. Divide 180 by 6, you get 30. Hope this helped!
