First turn them into improper fractions to make things easier: 31/8 and 155/4.
You would then do 155/4 divided by 31/8, and with the same-change-flip, do 155/4 times 8/31, which is 10

Answer:
x=50 ∠BCX=65
Step-by-step explanation:
The angles is a triangle add up to 180 so
70+45+∠BCX=180 so
115+∠BCX=180 (subtract 115 from both sides)
∠BCX=65
A line adds up to 180
so 2x+15+65=180
so 2x+80=180 (subtract 80 from both sides)
2x=100 (divide by 2)
x=50
