Answer:
x=0
Step-by-step explanation:
Solve for x.
5(x - 3) + 4(x + 3) = 3(x - 1)
Distribute
5x -15 +4x +12 = 3x-3
Combine like terms
9x -3 = 3x-3
Add 3 on each side
9x -3+3 = 3x-3
9x = 3x
Subtract 3x from each side
9x-3x = 3x-3x
6x =0
Divide by 6
6x/6 = 0/6
x=0

Answer:
90°
Step-by-step explanation:

The whole large triangle has angles 60 60 60 ( they sum to 180)
that means x = 30
then the small triangle on the right has 60 + 30 + y = 180
meaning y = 90 °
