Answer:
X=20
Step-by-step explanation:
The 3 angles all add up to 180º because they are a straight line.
3x + 80 + 2x = 180
5x + 80 = 180
5x + (80-80) = 180-80
5x = 100
5x/5 = 100/5
X=20
Hope this helps!

Answer: 48
Step-by-step explanation:
First, you multiply 75% by 64
Then, since 75% is 75 out of 100, you go ahead and multiply 75 by 64, then divide what you got by 100.
Now, you should have gotten 4800, so you divide 4800 by 100
So, your answer is 48
