Answer:
x = 43
Step-by-step explanation:
2x + 16 = 3(x - 9)
2x + 16 = 3x - 27
2x - 16 = 3x -27 (-16)
2x = 3x -43
2x (-3x) = -43
-1x or -x
-x = -43
-43/ -x = 43
Answer:
45
Step-by-step explanation:
The three angles of a triangle add to 180 degrees
3x+5x+4x = 180
Combine like terms
12x = 180
Divide by 12
12x/12 =180/12
x = 15
The smallest angle is 3x
3(15) = 45
