Answer:
i belive its 35/8 3.14
Step-by-step explanation:
sorry if im wrong
15=-4+z/3
+4 +15 = +4 -4 +z/3
cancels the 4 on the right side
19 = z/3
3 x 19 = z/3 x 3

I think the answer is z = 57
Answer:
54
Step-by-step explanation:
The sum of given angles must be equal to 360°
3x° + 2x° + 90° = 360°
5x + 90 = 360
5x = 270 divide both sides by 5
x = 54
You would do 45 divided by 9 which is 5. Then you do 5x7= 35 and that's your answer
