Step-by-step explanation:
The 3 inside angles of a triangle need to equal 180 degrees.
The angle below the 100 degrees would be 180-100 = 80 degrees.
Now you have 80 and 70, which equals 150 degrees.
Angle X = 180 -150 = 30 degrees
We can guess and check:
we know 105 tickets were sold for a total of 922 dollars
We know there were 10 dollar & 8 dollar tickets sold.
44(10)+64(8)
410+512
922 dollars
44 $10 tickets sold
