Answer:
2
Step-by-step explanation:
First, you do the subtraction 120-21.4 which is 98.7. So since you know its x^7, the number isn't going to be big. By guessing and checking, we start with 2. 2^7 is 128. We know that 1^7 would just be 1, so the closest whole number would be two.
180 - 64 = 116
116 / 2 = 58 :)
Check: 58 + 58 + 64 = 180
C.6 i think, sorry if it’s wrong but my reasoning was that 50 + 58 = 108 and the interior of a triangle is 180 degrees so then you would subtract 180 - 108 = 72, then i did some guess work plugging in the different answers into the equation and 11 x 6 + 6 = 72 which was the missing angle from before
The smallest number would be 4
the three numbers would be 4, 10, and 14, which would have a sum of 28
30% chance because 50+20=70 and 100-70=30. Since 30% is below 50%, I would say not likely.
