Answer 2

Answer:

36, 54 and 90

Step-by-step explanation:

4(x-1) + 3(2x-2) + 9x = 180 (angle sum property of triangles)

4x-4 + 6x-6 + 9x = 180

4x+6x+9x-4-6 = 180

19x - 10 = 180

19x = 190

x = 190/19

x = 10

So,4(x-1) = 4(10) - 4 = 36

3(2x-2) = 6(10) - 6 = 54

9x = 9(10) = 90

I hope this helps
