x = 50

Step-by-step explanation:

The three angles form a straight line so their sum is 180 degrees

x + 105 + 25 = 180

Combine like terms

x + 130 = 180

Subtract 130 from each side

x+130-130 = 180-130

x = 50

the mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents
