Answer: 90°
Explanation: the sum of all the angles in a triangle = 180. So 70 + 30 = 90 and 180-90=90
answer:
the decimal point shifts to the right to represent each multiplication by 10
Step-by-step explanation:
an example is 1.23*10
would give you 12.3 and if you multiply it by 100 it would give you 123
3x - 12
3(3x/3 - 12/3)
3(x - 4)
The answer is: 3(x - 4).
