Answer:
121
Step-by-step explanation:
The sum of the angles inside a triangle is always 180. The missing angle in the triangle must then be 180 -74 -47 = 59 degrees. The angles on a straight line add up to 180 degrees so x + 59 = 180. x = 180-59 = 121
It would be -13.6
I used my calculator for this,
-24.65 +25 - 46.75 + 32.80 = -13.6
the answer is c

3:4
That ratio would be 12:16, or 3:4.
