Answer 2

x=45

Explanation:

Statements | Reasons

90+x+5x=360 | A full rotation is 360 degrees.

90+6x=360 | I simplified (combined like terms).

6x=360-90 | I used subtraction property (minus 90 on both sides).

6x=270 | I simplified (combined like terms).

x=270/6 | I used division property (divided 6 on both sides).

x=45 | I simplified (performed the division).
