Hey there!
1.) let's remember that a acute angel is very tiny, it is less then 90 degrees. So we would want to find one of your options that would be very small.
46 would seem to be the answer.
x=46
Hope this helps you.
It will be 50,000 =10*5,000
It would be: 8 (x + 3) - 2x
= 8x + 24 - 2x
= 6x + 24
In short, Your Answer would be 6x + 24
Hope this helps!
